Top 7 Best Pool Clarifiers

Few things are more relaxing and enjoyable than a sunny afternoon spent swimming in the crystal-clear waters of your backyard pool. But what if your pool water isn’t as clear as you’d like? Maybe after opening for the season, your pool’s water seems to be murky and cloudy, making it less than appealing for swimming.

A swimming pool filtration system rids your pool of particles that can cause hazy, cloudy water. Sometimes, your pool filter needs help getting rid of small particles. That’s where pool clarifier comes in.

A Pool Clarifier is a liquid substance that contains polymers – chain-like molecules that act as coagulants on tiny particles that are too small for your filters to catch. Adding a clarifier causes these tiny particles to clump together and allows your filter to remove them through its regular process.

A clean and clear swimming pool is not only inviting but it also represents healthy water. Hence, it's important to choose and apply the most effective water clarifier in your swimming pool and make it a part of your maintenance. In this regard, we selected 7 of the best pool clarifiers you can use in 2021 and are easily available in the market today.
