So Your Pool is Cloudy?

Don’t Panic! There are a number of reasons that your pool could be murky. A pH imbalance, low chlorine, dead algae and the beginning of an algae bloom can all be the culprits. Lets address each issue so you have a better idea of how to attack your problems.

The summer is in full swimg and as the summer drudges on you will need to use more chlorine than the standard doses. When chlorine levels get low algae has an inviting pool to grow and flourish. The sun, swimmers and rainwater will all affect your pools chlorine level. We recommend checking your pools chlorine levels and chemical balance after any long hot weeks or heavy rain. Keeping a constant chlorine level in your pool is the greatest prevention against algae blooms.

If the pool is not green and test strips show pH out of range, you can adjust according to the strips and sometimes this will eradicate the haze in the pool. The best thing you can do is bring the water into the store and we can give you an exact regiment of pH adjusters to get your pH in check. A professional test is always the greatest guarantee and procedure to keep your pools chemical balance and clarity in order.

Dead algae is a suprisingly pesky problem. You use algaecides and shock to kill off algae but what do you do with the dead particulate matter that is floating around in your pool? Depending on your filter there are a few different options. Sand filters have the ability to use clarifiers to assist in filtering out the fine particulate matter of dead algae. Coagulants and alum salts like our Crystal Clear and Sparkle Pill are two different styles of clarifiers.

Coagulants meet with the particles in the water and “coagulate” to make the particle larger and easier to filter out.  Alum salts work by coating your sand and giving it more abrasion to pull out the finer particles. Both are highly effective and available in store. To eradicate the dead algae both salts and coagulants will work on sand filters but need to be used with caution if you have a cartridge filter. Cartridge filters are designed to remove very fine particle from the water and if clogged up with coagulants and salts they can build pressure and prevent passage of water. This can break a filter and create pressure build ups that can be dangerous. For cartridge filters we recommend using a Miraclear Pill which is a safe clarifier for cartridges or a steady cleaning on the cartridge as it filters out the fine particle may be necessary. You can also use enzymes like our Pool Pizazz to help break down and burn out these particles in cartridge and sand filter systems. DE filters should not need clarifiers. If your DE filter is not clearing haze out of your pool you  need a little more media added to the filters or to “bump” the system to clear the grids/fingers internally. All of these treatments should help eradicate haze caused by dead algae in the water.

The final issue we are going to discuss is the beginnings of an algae bloom. When chlorine drops off and algae begins its terror in your system it will first come in looking like a light white haze. This is the “seedling” stage of algae before it blooms. If your chemicals look in order and the chlorine has seemingly fallen low, you should shock the system to prevent algae from taking hold. If you are already seeing some light white and possible patches of green go with the following regiment. 2 Gallons or 2 Bags of shock for every 10,000 gallons of water in your pool. This is double the normal dosage and should prevent the haze from turning into an all out bloom in the pool. If the haze persists and turns green you need to triple your chlorine dosage to 3 Gallons/Bags for every 10,000 gallons along with the proper doses of algaecide. This should eliminate your problem.

We have touched on most of the primary reasons a haze or cloudiness will come into your pool. For any other solutions or thoughts please visit the store and have your water sampled by our professional water testing staff. And as always, happy swimming!

  1. The salt in a saltwater pool naturally inhibits algae. However, under certain conditions algae can develop in a saltwater pool. The first sign of algae in a pool is a slippery pool liner followed by the water turning a yellowish or greenish color. This is an indication of an algae bloom in your saltwater pool. When treating algae in your pool, it is not safe to swim in the water due to the increase of chemicals needed to kill the algae.
