Many pool owners love sharing their swimming experience with their pets. While it’s fun to watch dogs paddle around or cool off on a hot day, having pets in the pool can significantly impact water quality. One of the biggest concerns is the increase in phosphate levels, which can contribute to algae growth and even mold formation in the pool.
Phosphates are naturally occurring compounds that serve as a food source for algae. While some phosphates enter the pool from rain, leaves, and lawn fertilizers, pets can also be a significant source. When pets swim in a pool, they introduce phosphates in several ways:
Fur and Dander: Pets shed fur and skin cells, which break down and contribute to organic material in the water.
Saliva and Urine: Even if your pet doesn’t urinate in the pool, saliva contains phosphates that can leach into the water.
Dirt and Oils: Pets carry dirt, oils, and debris on their paws and coat, which washes off into the pool.
Pet Shampoos and Conditioners: If a pet has recently been bathed with shampoos or conditioners, these products may contain phosphates that dissolve into the pool water.
Phosphates act as a fertilizer for algae, making it easier for algae to bloom and spread in your pool. Once algae take hold, they create an environment where mold and bacteria can thrive. This not only makes pool maintenance more challenging but can also lead to water clarity issues, clogged filters, and slippery surfaces.
If you enjoy letting your pet swim in the pool, there are steps you can take to reduce phosphate buildup and maintain water quality:
Rinse Pets Before Swimming: Giving your pet a quick rinse before they enter the pool can wash off dirt, oils, and loose fur.
Use a Pool Skimmer and Filter Regularly: Remove fur, dander, and debris from the water as soon as possible.
Maintain Proper Chemical Balance: Regularly test phosphate levels and use phosphate removers if necessary.
Shock the Pool After Heavy Pet Use: This helps break down organic materials before they contribute to algae growth.
Limit Swimming Time for Pets: Reducing the frequency of pet swimming can help keep phosphates under control.
