Types of Pool Chemicals Explained

Written By: poolgeek.com

Pool Chemicals are essential to keep your pool properly balanced, which will not only give swimmers outstanding water quality, but will keep your valuable pool equipment and surfaces safe. The most important chemcials are ph balancers, alkalinity balancers, algaecides, sanitizers, clarifiers, metal controllers, foam removers and pool shocks. In order to properly apply these chemicals, however, you must use testing strips or take a water sample to your local pool professional. These strips are available from many different manufacturers, and give you highly accurate results in minutes, eliminating any guesswork when balancing your pool water.


pH Balancers


BioGuard Balance Pak 200

pH balancers are critical to maintaining the proper pH range of 7.2 to 7.6, which determines the overall health of your pool. If too low, your pool plumbing and surfaces will start to severely corrode, while too high a level will cause ugly scale deposits to grow along with cloudy water. An unbalanced pH will also cause swimmer eye and skin irritation as well as reduce chemical efficiency. pH balancers will, depending on the product chosen, raise or lower your pool pH in steady increments to get it into 7.2 to 7.6 range.


Alkalinity Balancers


GLB Alkalinity Up

Alkalinity balancers are another critical part of pool chemistry, and help keep your pool in the optimal 80-160 ppm range. This will not only result in a more comfortable pool for swimmers, but will eliminate the dreaded "pH bounce" that makes proper pool balancing all but impossible. If alkalinity is too low, pool plumbing and surfaces will start to corrode, while too high a level will cause ugly scale deposits and cloudy water conditions. Also like unbalanced pH, an unbalanced alkalinity will also cause eye and swimmer irritation and chemical inefficiency. Depending on the product selected, alkalinity balancers will raise or lower alkalinity levels in steady increments to the optimal 80-160 ppm range.


Algaecides


Pool Frog BAM Algaecide

Algaecides are the easiest and most effective way to prevent and remove all types of algae growth from your pool, which can ruin water quality and clog pool filters. Algaecides are available in both granular and liquid formulas to fit your needs or budget, and come in a wide variety of formulas to tackle green, blue-green, mustard and black algae types.




Sanitizers


BioGuard Silk Smart Sticks

Sanitizers are the most important chemical additive you can add to your pool, removing bacteria and other harmful contaminants from pool water. The most common sanitizers are chlorine and bromine, although there are proprietary sanitizers available from several brands. They are available in several forms, including liquid, granular, tablets and sticks to fit your pools specific needs or equipment.




Clarifiers



SeaKlear Natural Clarifier

Clarifiers are another handy pool chemical that quickly eliminates cloudy water conditions in your pool, restoring it to its former beauty. Standard clarifiers attract together microscopic particles into larger ones, allowing your filter to remove them. Flocculant clarifiers also attract microscopic particles into larger ones, but its formula sinks them to the pool bottom for easy vacuum removal. Either type will produce the jewel-like brilliance you remember in just minutes.




Metal Controllers


Jacks Magic The Purple Stuff

Metal Controllers enable pool owners to remove copper, iron, manganese and other metals from their pool water, preventing staining and water discoloration. These chemicals are especially useful in areas with hard water, although metals can get into your pool through other means. Metal preventors stop metals from getting into your pool, while metal removers eliminate metals already present.




Foam Removers


BioGuard Anti Foam

Foam Removers are an easy and affordable way to remove annoying foam buildup on your pools surface caused by heavy swimmer loads. Products such as deodorant, soaps, lotions and other cosmetics from swimmers creates this foam, which foam remover can cut through in just seconds to restore your pool to its former beauty.




Pool Shock


Omni Crystal Clear Multi Shock

Pool Shocks are necessary to sanitize your pool after heavy swimmer loads or simply when your pool sanitizer is overwhelmed by the contaminants in your pool. Chlorine-based shocks eliminate any bacteria or other organics from your pool water, while Monopersulfate or MPS shocks give you the same results without disturbing your pools chlorine levels. When used as part of your routine pool maintenance, your pool will stay clean and healthy throughout the pool season.

Title: How to clean dead algae in the pool

Title: Re: How to clean dead algae in the pool
“Hi Norma! A sand filter will not be able to remove all the dead algae in your pool because it does not have the capability. Since the floc worked for you, I would recommend you continue to use the product until the algae is gone. Using a floc will gather the algae particles and make them sink to the bottom of the pool so that you can vacuum them out. Along with the floc, you can use a Filter Aid. It will help in the filtration of small particles that would normally be missed by the filter. If you type “Filter Aid” in our search bar you will be able to view all of the product options. ”

Title: Very Cloudy Water

I am having a hard time keeping my pool clear. Right now you can barely see the bottom. How can I clear this up? The temp here has been 100 + for a week or 2.



Answers
by Aurelie Martins, Brighton, MI on 7/2/2009
Title: Re: Very Cloudy Water
“Hello Fred! There could be several factors that are causing your pool water to be cloudy. Your pool water chemistry could be one of the reasons; lack of shocking, high pH, high Total Alkalinity, and high Calcium Hardness. This can cause the chlorine to react slowly and therefore not control algae and bacteria as well. If it has been over 100 degrees for several weeks, the high Calcium Hardness can cause cloudiness. I would begin by testing your pool water and adjusting your chemical levels accordingly. You will want to shock your pool up to 10 PPM and then test your chlorine levels again. The chlorine levels should be stabilized at 3 PPM for a couple of days. The MOST IMPORTANT THING is to run your filter for 24 hours until your pool water clears up. If, after shocking your pool, the chlorine does not stay at 3 PPM for a couple of days or the water continues to be cloudy, you will need to use a water clarifier. ”

Title: Re: Small Pool Chemicals
“Sherry, with any pool you need to keep the chlorine level between 2-4 ppm in order to keep the water clear and safe to swim in. Also, you need to filter the water at least 12 hours a day during normal operation and 24 hours a day when cloudy. We suggest purchasing a simple test kit and performing those tests daily to ensure your water is sanitized (chlorine) and balanced (pH). Good luck and I hope your niece enjoys her swim.”

Answers

Title: Re: How To Treat Visible Algae
“Hi Maria! To treat visible algae, you do not have to drain your pool. We recommend either of these two products for your algae problem: OMNI ALGAE TERMINATOR This is a non-staining algaecide that will help kill your pool algae. It can be used with chlorine or bromine pools and with all surfaces and filter types. BIOGUARD BANISH Destroys all types of pool algae. Approved for both chlorine and bromine pools and does not affect pH levels, so no readjusting is necessary after application. To treat the visible algae: 1) Shock your pool. We suggest Breakout Extra, BurnOut Extreme, or BurnOut 35. You will want to follow the product directions to know what amount to add to your pool. 2) Allow your pool water to circulate for 1 hour. 3) With the pump and filter operating, apply either BioGuard Banish or Algae Terminator according to the product directions. You will want to apply the product to the pool water with the areas of heaviest algae growth. 4) Continuously circulate the pool water for the next 24 hours. 5) Afterwards, thoroughly brush the pool surfaces. If you have concrete surfaces, you can use a stainless steel brush. For all other surfaces, the plastic brushes are recommended. 6) Prior to re-entry, test the chlorine level. Do not re-enter the pool until the chlorine level is between 1-4 ppm. 7) In cases of persistent algae, repeat brushing and application after 2-4 days. ”

Title: Grey film not budging

There is a grey film on most of the surface of our pool which will not brush off. The water is clear. Several weeks ago I used a clarifier, and I think these particles may be from that. However, the tiny particles seem to have adhered to the pool surface in most places. You can see brush marks from the vacuum, looking like it was coming up for awhile and then in the middle of the vacuuming it stopped budging. Is that possible? I am stumped. Any help would be appreciated.

Title: RE: Grey film
“The vertical sides of the pool are made of fiberglass, but the entire "bowl" - the lower sloping part of the sides and the bottom are painted concrete. Both areas have the film. We are on city water. Our winter cover is porous and when we first opened the pool the water was very acidic, according to our pool supply store clerk because of acid rain. When we installed the ladders, they turned from chrome-colored to copper colored, so this may be a clue. Whatever caused it, I can't figure out why it came up at first and then seemed to stop, and how can we get it off? Thank you!”

by Aurelie Martins, Brighton, MI on 7/24/2009
Title: Re: Grey film
“Yes, acidic rain water can affect the pH in your pool water. The grey stain you have could be caused by a number of things. Often, in fiberglass pools, copper stains can appear grey to bluish black. If indeed you have a copper stain problem, Jack’s Magic Stain Solution 2, ProTeam Metal Magic, and GLB Sequa Sol are all good products to use to remove them. However, I would recommend using Jack’s Magic Stain ID Kit first before you waste money on chemicals that may not work. It will give you an easy way to treat the stain problem by applying the proper treatment. It gives you 4 test chemicals to use on the stain problem; whichever one quickly cuts through the stain is the product that will effectively remove it. Since you describe a film, it could also be due to the water clarifier that you used. What kind was it? If you do use the Stain ID Kit and still get no results, let us know, we can offer other options. Hope this helps!”

Answers

Title: Re: Pools with well water
“Hello Marion! Your pump should run long enough to cycle the pool water twice. This will vary by pool size but it can be anywhere from 8 to 12 hours. For an algaecide, I would recommend BioGuard Back Up Algaecide. It prevents a variety of algae growth and will not evaporate. It’s also non-staining and won’t affect the pH levels. For a clarifier, I would recommend BioGuard Polysheen Blue. It helps with the filtration of cloudy water and works with all pool and filter types. It also won’t affect the pH level. Since you are using well water, you could use a pool metal control product like Natural Chemistry’s Metal Free. Sometimes with well water you can get dissolved metals such as iron, copper, magnesium, and manganese in the pool water that cause staining of pool surfaces and water discoloration. You can use this product when you first fill your pool, at the beginning of the pool season, and at the end of the season to prevent discoloration. ”

The store that I work for is a bioguard dealer so it is Soft Swim that I work with. My QUESTION is, there used to be a product for bioguard called Soft Swim Assist that was used in a closed loop to clear out the water mold that seems to constantly build up in the lines. I am nearly positive that this product was just 1" tablets under a different lable but don't know for sure so I can't justify having people with a clairifier demand try using chlorine tabs (even in a closed loop) to try and fix it and there are no other products out that I know of to fix a demand.

You'll also want to use a flocculate treatment followed by brushing of the surfaces. Then, retreat the pool with Soft Swim A, B, and C. ”
