During the Monsoon season in Arizona, the wind is responsible for blowing a lot of contaminants around, making it more likely that you will see an algae bloom, or possibly a few through out the summer. Wind carries a lot of things that can cause algae to grow, like algae spores, fertilizers, dirt and plant debris. Even birds bathing in the water feature can promote algae growth.
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. Many algae outbreaks take place in water with perfect chemistry, as the algae has become immune to the chlorine.
There are many products available to get rid of algae. Phosphate removers and sometimes a specific algae control solution is required, 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.
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. Its eco friendly, registered with the Environmental Protection Agency [EPA] and certified by the National Sanitation Foundation [NSF]. It has been doing a very good job for me in the pools I've tried them in, eliminating all types of algae. 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.
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 its 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.
