Best Selling 3 Inch Chlorine Tablets

Let’s begin with an important chemical that’s part of DIY pool service that helps keep your pool water clean from algae and other microscopic critters that will inhabit water if left untreated. That’s right – chlorine tablets! Read more about the best pool chlorine brand and how this chemical works.

Best Selling Pool Shock

Next on our shopping list is pool shock. Pool shock is another key swimming pool chemical that is required weekly, especially during months when people are swimming a lot. Shock treatments help control the germs and bacteria that can cause illness.

Best Selling Pool Algaecide

Algae can show up in your pool water overnight, especially during the summer when the water gets close to 90 degrees. Another duty of DIY pool care is keeping algae under control. This requires brushing the pool walls and often treating the pool water with an algaecide.

Best Phosphate Remover

When algae patches keep showing up on your swimming pool walls or steps, it might be because organic debris such as leaves and dead bugs are loading up your pool water with phosphates that algae love to feed on. If this is happening then it’s probably time to treat your pool water with phosphate removal on a weekly basis.
