Identifying Suitable Pool Sanitizers

Published

on

Pool Industry New Spa and Pool Products

Recently, there has been an increase in pool sanitizers in the crowded pool industry. There is an introduction of new techniques after every few months, confusing the customers. The best decision is to ignore all the talks of the new commodities every other time. For years, UV-C and Ozone have been the most common commodities in the market. The problem is they keep on disappearing and appearing. Currently, all the focus is on the Advanced Oxidation Process (AOP).

Identifying Suitable Pool Sanitizers

Pool experts are conversant with various selections, but it is mind-blowing to keep up with the many new market trends. Each year there is the introduction of a new perfect technique. This makes it even harder for the experts in prescribing to their clients what system is best. It further raises the question if there is a perfect system designed for every individual.

Aim of supplemental pool sanitizers 

Over the years, pools have used chlorine as the only sanitizer. The main question is why to use supplemental sanitizers while chlorine has done the job perfectly for years.

The reason behind this is that these sanitizers provide three primary advantages;

  • Get rid of impurities resistant to chlorine
  • Clean water
  • Minimizes chlorine use

Supplemental pool sanitizers like Ozone, UV-C & AOP offer these benefits at different levels.

The key issue is to get pool water clean and safe. Pools contain more impurities than we can imagine, that Chlorine, on its own, is unable to destroy all these impurities. Reports indicate thousands of cases on bugs like cryptosporidium that are repellent to Chlorine. Current researches have also shown swimmers’ contribution to the impurities in a pool. Some swimmers don’t take a pre-shower; rather, they clean in the pool water. Introducing these sanitizer makes Chlorine more effective and eliminates all impurities making the water clearer.

Primary Upgraded Sanitizing Compounds

Ozone technique

Ozone is the most common sanitizer. The founders of ozone system, DEL Ozone, have created ozone generators meant for pools & spas from 1975. The arrangement produces a strong oxidant, comprising three oxygen atoms. The unstable molecule reacts with oxygen impurities in water hence eliminating them. It is a safe method to clean the pool by destroying pathogens and other contaminants through the Oxidation process.

UV-C Light Sanitizer

UV-C tampers with the reproduction and genetic structures of microorganisms to prevent bacterial infection. Furthermore, it increases the levels of free chlorine by reducing chloramines in the water. The best system increases exposure length to the UV rays for effectiveness. The UV-C Light technique does not cause oxidation rather disinfects the impurities. This means that it has nil effects on water balance, and direct installation with the pool system is possible.

Advanced Oxidation Process

As the name suggests, it is an advanced process. It combines both the effectiveness of UV-C Light and Ozone to bring about a new reaction. To achieve this, it contains very reactive hydroxyls molecules that eliminate 99.9% of dangerous pollutants. The oxidation process occurs immediately, making AOP the strongest product in the market.

How to figure out your best sanitizer choice

With the numerous great varieties, it isn’t easy to find the right one. Each system has a different “personality.” Every system is suitable in one or more aspects.

Pool professionals should consider the following when purchasing an advanced sanitizer. The first consideration is the one you would normally opt for. The second is to select one that will fulfill the purpose of installation. Lastly, it should be able to solve your client’s problems. Choose pool sanitizers designed to cater to your needs and client’s desires. The following can be suitable to determine the best system;

  • If the aim is to reduce chlorine use
  • UV-C brings no extra additions to the water. It minimizes the levels of chloramines but has little effect on the reduction of chlorine use.
  • AOP & Ozone minimizes the use of chlorine with AOP having the strongest effect.
  • Both get rid of chloramines to maximize the effects of chlorine and hinder any sanitization after effects.
  • UV-C is cheaper for residential techniques, both fitting and machinery needed.
  • On the other hand, ozone is less costly compared to AOP and has a developed technology.

New Constructions or Reconstructions

UV-C is best for reconstruction and fits well with any pool. They easily adapt to the present system and no dedication line required for its fitting. In this system, it is important to note that the lamps will need regular replacement.

New pool constructions allow for the installation of an appropriate system with better pressure and flow rates regulations that will serve the pool for a long time.

Water Safety

  • AOP & Ozone quickly oxidize giardia, crypto, and other chlorine repellent bacterium.
  • AOP is quicker and effective compared to UV-C, Ozone, and even Chlorine.
  • Is it beneficial to find the appropriate system for every pool

As noted, pools need to have a supplemental sanitizing system as all studies show they improve Chlorine effectiveness and water safety. It is further recommended by the CDC & needed on the majority of commercial fittings.

All supplementary sanitizers destroy microorganisms by reducing the use of chlorine and improving its performance. This makes the pool safer and healthier for swimmers. Despite many options, with the above factors, it is possible to find your fit for pool sanitizers.

Pool Stains - What They Mean and How To Remove Them - Steps for Removing Pool Stains

There is nothing worse than a dirty pool than perhaps a stained pool. Identifying pool stains and what they mean is important. There are different approaches towards cleaning certain types of stains. Figuring out what is causing the stain is often possible by looking at the color of the stain. Various maintenance issues have a tendency to create a certain colored stain in the pool. Identifying what those colors indicate can help you locate the source of the problem.

Pool Stains - What They Mean & How To Remove Them - Pool Stain Comparison Chart
How well do you know your pool stains? View our Pool stain comparison chart.

Types of Pool Stains & What They Mean

Pool Stains - Green Brown Stains

Green Brown Stains

This type of pool stain is typically caused by decaying organic matter such as leaves and debris. Allowing leaf debris to accumulate at the bottom of the pool can cause an unsightly greenish-brown stain.

Stain Removal

To remove an organic stain quickly, sprinkle granular chlorine shock directly on them. On vinyl-liner pools, you’ll want to pre-dissolve the shock first in a five-gallon bucket of water before pouring it on and brushing it in.

Red Blue Stains

Berries cause reddish-blue pool stains. If you have berry trees in your backyard, this could very well be the culprit of red-blue stains in your pool. As the berries decay, the juice and skin of the berry can cause a stain that looks almost purple in color.

Again, you’ll want to take the same approach as removing organic stains. Brushing the liner with shock is your best option here and should remove the stain quickly.

Red Blue Pool Stains
Blue Green Black Stains in your pool

Blue Green Black Stains

Blue-ish Green-ish Black stains on the bottom of your pool could very well be berries too. However if there aren’t any berry trees in close proximity, high levels of copper could be the cause. If you have copper piping as part of your pool equipment setup, corrosion could cause stains that are of a blue-green black composition.

Mineral Based Algaecides

The leaching effect of copper intrusion has been known to cause stains that can be difficult to remove. Heavy doses of copper-based mineral algaecides have also been shown to produce similar stains. There are products such as Stain Free, A+ Stain Remover, and Jack’s Magic Blue Stuff that do an admirable job of removing stains on vinyl liners.

Green Brown Red Stains

Pool stains that are greenish brownish red usually indicate the presence of iron in the pool. As iron rusts, it has a tendency to leave a rusty greenish brown-red stain. This is true in all types of pools.

Leaching Metal Stains in the Pool

Metal leaching can occur that produces a stain from the pool coping, decking material, and a variety of other sources. Marble, granite, and flagstone all contain the mineral Iron and can leach into your swimming pool after a heavy rainstorm. Stains of this nature also occur without proper waterproofing.

Removing green brown red stains in your swimming pool
Brown Black Purple Stains - Manganese staining

Brown Black Purple Stains

This type of stain may look like a big bruise on the bottom of your pool. Stains that are brownish, black purple tend to be the cause of high levels of manganese. This can actually come from the local water supply, especially if the source is well water. Superchlorination is the best way to handle the problem as it oxidizes the manganese to a rust like substance that can be vacuumed off the pool floor. The next step should be cleaning out the pool filter as manganese can cling to surfaces.

Testing for Organic Stains & Metal Stains in Pools

You can easily remove organic stains with a little elbow grease and the right supplies. The typical field test pool contractors use for determining what type of stain they’re dealing with is to simply rub some chlorine on the stain to see if it dissipates. Metal doesn’t react to chlorine. This is why components such as pool ladders are made of metal. If the stain doesn’t react to the stain, then it’s probably metallic in nature.

One way to test if it’s a metal stain that you’re dealing with is to apply some ascorbic acid to the stain. If the stain is removed or at least reacts (lightens) in the presence of rubbing with Vitamin C powder, you have a pretty good indication that it’s a metal stain.

Plaster hydration stains

Hydration Stains in Pools With a Plaster Interior

These stains tend to look like metal staining but are present in plaster pools. Since these types of stains can be difficult to remove there are some things you need to know first. Plaster hydration stains occur when the pool plasterer plasters the pool while the form isn’t completely dry or moisture or humidity is present. If you’re certain that the stain isn’t metallic (stain doesn’t react to ascorbic acid) then acid washing the pool interior is the best option for removing hydration stains.

Removing Organic Pool Stains

Once you’ve determined that it is actually an organic stain that you’re dealing with, chlorine is going to be your best friend here. Honestly, if you had the right amount of chlorine to begin with, you probably wouldn’t even have an organic pool stain. Superchlorination of the water is your best option for dealing with organic stains. Shocking the pool is going to help remove stains caused by leaf debris and decaying organic material. The go-to solution for many pool contractors is to use Cal Hypo (Calcium Hypochlorite Shock).

  • The process here is to test and balance your pool chemistry. Your ideal comfort zone for alkalinity is going to be in the range of 100ppm to 150ppm with 125ppm being the sweet spot.
  • The next step would be to shock the pool. For smaller stains a regular dose of Cal Hypo should do the trick. For larger pools or larger stains you’re going to want to up the dose. The typical regimen is 3 pounds per 10,000 gallons.
  • The third step in the process is brushing the pool to physically remove the stain. On vinyl liners you’ll want to be careful here making sure not to tear the liner while attempting to clean it.
  • Next, run your pump overnight and allow the water to circulate throughout the swimming pool. Make sure to do this for at least 8 hours.
  • Brush again in the morning. Repeat the entire process until satisfied with the results.

Removing Metal Pool Stains

The process of removing metal pool stains is a bit different than removing organic stains, however, using the correct products will greatly assist you in getting rid of metallic pool stains. There are a number of products on the market as we mentioned previously that can assist you in removing metal pool stains. Consequently, finding the right product to use all has to do with first identifying which type of pool stain you actually have.

Cleaning a pool stain is only half the problem. Keeping them from coming back is the real issue. Recurring pool stains can be a real nuisance. Moreover, people are less concerned with cleaning a stain and more concerned about why it occurred to begin with. Ideally, people want to keep mineral and metal stains from coming back.

Dealing With the Trichlor Shortage Head On

Published

on

Dealing With the Trichlor Shortage Head On

The recent fire that destroyed the chemical plant in Louisiana is the main reason for the current chlorine shortage. As a result, a good percentage of pool companies were adversely affected. At the same time, some pool companies remained unaffected by these events and have been able to carry on business as usual. Such companies relied on other pool sanitation systems like saltwater systems and baquacil.

Dealing With the Trichlor Shortage Head On

But generally, the shortage of chlorine is a big challenge for many pool owners. There has been a significant rise in the price of chlorine due to increased demand.

How did pool professionals deal with tricholor shortage?

Once the news hit home, pool experts came up with several strategies to deal with this sudden shortage of chlorine. President of Patio Pleasures Pools & Spas, Rene Huston, said that trichlor shortage forced them to stock up in excess. This way, they would still have supplies in the next swimming pool peak season. Although this was a good idea, they realized that the demand was too high. In particular, the demand was three times than what we would sell in normal seasons.”

Most pool companies stocked up the chlorine in excess to deal with the shortage. Even so, this strategy also comes with other challenges. When you decide to stockpile chlorine, you need to create safe storage space. As a result, pool product suppliers have had to expand their warehouses to accommodate excess stock. Aside from creating a stock house, you need a lot of money to purchase chlorine in bulk. Unfortunately, very few pool experts have enough cash to stockpile.

What were the early signs of chlorine shortage?

People started noticing the shortage of chlorine by a sudden hike in prices. Before, pool owners bought a 50-lb buck of 3-inch unwrapped tablets at $70 to $75. Last year., the price rose to $125. Thus, pool owners had to pay almost twice what they used to pay to get chlorine tablets.

CEO/RMO of Cline Commercial Pool Service in California, Lori Ann Cline, says that she received a notice that the price of chorine would rise by approximately 15 to 20% during summer. Therefore, her company had no choice other than increase their prices to retain their profits. Contrary to popular belief, the increase in prices has not helped them deal with scarcity. In fact, most of their suppliers are currently reducing their purchases every week. So, they cannot buy as much chlorine as they would wish. Unlike before, they cannot order multiple buckets of trichlor.

Dealing with the situation beforehand

The owner of Richard’s Pool Service, Richard Garnai, says that the shortage of trichlor has not been a big problem for them. They already had a solid plan for dealing with the shortage. Their suppliers advised them to purchase trichlor in bulk. This way, they would be able to meet the expected surge in demand during summer. If they run out of stock, he considers manufacturing the chemical himself. Additionally, he plans to use cyanuric acid and liquid chlorine if he runs out of stock.

Garnai advises pool experts not to depend on tabs this summer. He says that looking for other options is a great idea. Trying to reduce the use of chlorine tabs is a great idea to deal with this problem. Some of the alternatives to trichlor include calcium hypochlorite and liquid chlorine. Although bromine is also a great alternative, it tends to degrade when exposed to sunlight.

Education programs

At the moment, it is essential to educate customers about this sudden shortage. Most customers are angry about this whole situation. Consider informing your customers that you are suddenly experiencing a chlorine shortage, and it would be best to look for other alternatives. Explaining the sudden increase in prices is also a good idea. Pool professionals are also encouraging customers to stock up tabs before summer. Fortunately, most customers are responding positively.

Using alternatives to chlorine

At present, there is a broad spectrum of techniques that can help you lower chlorine usage in your pool. These techniques help pool experts deal with the trichlor shortage well. When reducing the pool’s dependence on chlorine, the first thing to do is keep the pool in good condition. Using UV, Ozone, and AOP pool systems also helps you reduce chlorine usage. Consequently, pool experts are trying to encourage customers to consider other pool sanitation alternatives. Fortunately, most customers are responding positively. Nonetheless, pool experts hope that they won’t experience these challenges in demand and supply come next year.
