Why is there Algae in my Pool Each Week?

Getting Algae constantly in your pool each week can be very frustrating. Below are several methods to prevent algae from forming in your pool and all of these methods are tested and proven to work.

BORATES:
Lower Chlorine usage: The Borate helps reduce chlorine usage by eliminating Carbon Dioxide and also by keeping the pH stable. Chlorine last longer when the pH is right at 7.6-7.8. When the chlorine is in the ideal range the killing element in chlorine the HOCI is at the most balanced percentage so the chlorine in a pool with a pH of 7.4 is 30% more effective than in a pool with a pH of 8.0. This is a big factor in creating the safest swim environment and the borates will keep the pH much more stable and in turn make the chlorine much more effective.

pH is stable: The pH won't change much in a pool with Borate in it. So, if you have a Salt Water Pool this is a must since the pH tends to rise dramatically. In fact, in a Salt Water Pool the pH can rise to over 8.4 very rapidly. You will find yourself putting tons of acid in each week just to keep the pH below 7.8. With borates in the pool the pH will be stable and easy to control. It is a must for a pool with a Salt Water Generator. It also will keep your salt cell from building up calcium rapidly since is sequesters the Calcium in the water. This means the salt cell will remain clean and your salt system will run much more efficiently.

Less Algae growth: Boric Acid is a known Biostat. This prevents the algae cell from forming and multiplying. Thus, a pool with a Borate level between 30-50 ppm will prevent algae growth. Since borate prevents the algae cell from growing, algae blooms will be a thing of the past. No more algaecides or shocking the pool, algae just won’t grow in your pool any longer.



POOL RX:
PoolRx is a simple way to keep your pool algae free all season long. It is also effective in cleaning a green pool and a side benefit of the product is that you will use less chlorine in the pool all season long. In this Podcast, I talk to Fred Schweer VP of Sales at PoolRx Worldwide about using PoolRx at the beginning of the season and to clean up a green pool. He also offers tips to pool service professionals on how to market and sell PoolRx to the customers on your route.

PoolRx is a Mineral Technology does two very simple things when used in your pool or spa; it eliminates all algae and will allow you to use less chlorine during the pool season. The active ingredient is Copper Sulphate Pentahydrate (chelated).

What Chelated means is that the metals in the PoolRx have been bonded to form two coordinated bonds similar to what Metal Sequestering Agents do. This means that the Metal Ions will remain in the PoolRx unit with no metal ions being introduced into the pool or spa water. PoolRx is Chelated so the metal ions stay within the PoolRx unit itself.


SODIUM BROMIDE:
Any Sodium Bromide product will work effectively in treating Yellow Algae. As long as the active ingredient is Sodium Bromide it will work in clearing up the algae.

Bring the chlorine up to what we refer to as "Blazing High" if it is at zero ppm. One common mistake is not starting with a good chlorine level. Sodium Bromide will convert the chlorine to
Bromine and the Sun will also burn some off as the Bromine Molecule does not bond with the Cyanuric Acid molecule (conditioner does not protect Bromine) so even more chlorine will burn off. And some of the chlorine will be "eaten" or used up by the Yellow Algae itself.

So, it is very important to have a good chlorine level first 5-10 ppm and to also add a gallon of liquid chlorine or Clorox bleach with each 4 oz. capful of Sodium Bromide. Otherwise, you might have an even worse problem.


ALGI-BAN FOR BLACK ALGAE:
Black algae can be tough to treat and get rid of as the roots extend into the plaster and even if you keep high chlorine levels in the pool the black algae can still persist. It doesn't help that the heads of the black algae also offer a protective film that keeps the chlorine from killing it.

The most effective treatment in a white plaster pool or older color plaster pool is with granular Trichlor which is the same chemical found in the 3” tablets but in granular form. A popular brand is the HASA Algi-Ban. You would aggressively brush the heads off the black algae and then sprinkle the granular Trichlor even on the pool bottom, covering as many black algae as possible.

Unhook any automatic cleaner and turn the system off for 24 hours if possible. The chlorine level will be really high so no swimming for at least a week or more.
