For some reason, each year around the time we start to see triple digit temperatures, I see algae starting to grow. Even though the water chemistry is perfect and chlorinated, there it is. I am usually able to kill it off with a phosphate treatment and an ammonium chloride algaecide. But often it recurs.
The most common is mustard algae, seen in the picture on the left. Its name comes from the yellowish color, it often grows on walls and easily brushes away. Simply adding shock will not kill the algae, since in my case, the water is spot on. Its immune to the chlorine. There are many products available to get rid of algae and it may take more than one attempt, or even a different kind of algaecide altogether before its gone. For example, if copper doesn't work, you will have to try something else, depending on what type of algae is growing in the pool. Did you know that adding too much copper based algaecide can stain your pool plaster? Copper metal stains are purple in color and require special stain removers and an acid wash to remove them. Too many times I see people adding more than the recommended amount and the stains are bad.
The specially treated alloy cylinder is packed with a mineral formulation. The purifiers minerals immediately dissolve out of the cylinder and form a stable, residual amount of minerals in the pool water, effectively killing algae. The active minerals free up available chlorine, meaning less chlorine is required to burn out contaminants. That's is a good thing. Using less chemicals makes the water more enjoyable to swim in. Less chemicals means your water is less irritating to the skin, eyes and nose. Its hard to find a reason not to like this product. Give PoolRx a try, it will definitely make a difference for you this summer.
I have recently started using a product to control algae called PoolRx. Instead of adding harsh chemicals and metals to the water, PoolRx is a mineral purifier. It has been doing a very good job for me in the pools I've tried them in, eliminating all types of algae for up to 6 months. In Arizona, that means the whole swim season, which is why I love it when I run into recurring algae problems. Available in three different sizes, PoolRx can treat small pools between 7,000 gallons and 20,000 gallons and larger pools up to 35,000 gallons with the PoolRx Extreme mineral purifier. Pools larger than 35,000 gallons can be treated with an extreme PoolRx and the addition of a booster pack. A tiny purifier is also available, which can be used to treat in ground spas and water features. Simply placing a PoolRx purifier into the strainer basket of the pump and it will work up to 6 months.
