How to control algae growth in your pool by eliminating phosphates

Swimming season still has plenty of surprises left in store for many homeowners, which is why it’s vital that these individuals contact their Phoenix pool service technicians regularly to keep their backyard oasis in tip-top shape as the season comes to a close. One of the biggest issues that pool owners will face throughout the year is the occasional algae bloom, which can leave the pool water looking green and can make for an unhealthy swimming environment. Luckily, Poolman professionals can control the outbreak quite easily by regulating the level of phosphates found in the pool.

What are phosphates?
Phosphates are biological building blocks that are used in everything from cleaning products to foods, but they can also act as a means of nourishing algae spores and allowing them to reproduce and create the green, cloudy water that’s a serious hazard for pool owners. According to, phosphates are compounds of the nonmetallic element phosphorus, and they are a primary food source for aquatic plants. The problem with phosphates is that they are constantly being reintroduced to pool water from dust and debris, as byproducts from lawn and garden fertilizers and even from fresh water being added from a water leveler.

How are phosphates controlled?
There are a number of products that Poolman professionals use to control the water balance of pools and reduce the amount of phosphates present that could lead to algae blooms. According to, phosphate levels should be kept at 100 parts per billion or lower, and pool service technicians typically measure the phosphate levels of the pool and add a series of phosphate-reducing products to the water to ensure that the pool is at the appropriate levels to stay clean and healthy throughout swimming season.

In addition to keeping a close eye on phosphate levels, regular maintenance plays a vital role in reducing the presence of these compounds and lessening the chances of an algae problem. Regular pool cleaning tasks like removing leaves, twigs and other organic material as soon as possible, as well as cleaning filters and pump baskets regularly can stem the tide of phosphate levels. Last but not least, preventing the drainage of water from outdoor plants and the surrounding lawn can also decrease phosphate levels and support the overall health of the pool.
