Actually, algaecide does not do the actual killing of the algae. It strips the cell walls of the algae and allows the chlorine (hypochlorus acid) to do its job. So algaecide works great as a preventative since it makes the algae much more vulnerable to the chlorine. I typically add 4-6 ounces of Polyquat algaecide per week as a preventative. A side benefit of Polyquat is that it also acts as somewhat of a clarifier.

How much chlorine do I add to kill algae?

The amount of chlorine needed to kill algae in a pool depends on the severity of the algae bloom and the size of the pool. It is recommended to shock the pool with a higher dose of chlorine than usual, following the manufacturer's instructions on the product packaging. Additionally, consider using an algaecide in conjunction with the chlorine for more effective treatment.


Why do you get heavy algae growth in your pool a day or two after using algaecide?

I just had a similar problem so I'll tell you what cleared mine up. I wasn't using enough Algaecide in my pool to correct the problem. I have about 32,000 gallons and the pool company recommended a quart and a half of an algaecide with 7% copper. I found mine at WalMart and it only had 3% copper, but it worked fine. Some of the products do not contain copper, they informed me, and copper is a necessary ingredient to kill the algae. Pour it in and let it sit overnight. Then vaccumm to WASTE the walls and bottom. The algae is so fine that it will remain in your filter and keep flowing back to your pool if you vac the pool in the normal way. The Copper ingredient bonds to the algae for removal. After the pool is clean, add a few ounces of the algaecide each week. I need to add about 6 oz. Let us know if this works for you.


Can you vacuum pool after algaecide is added?

It's generally recommended to wait at least 24 hours after adding algaecide before vacuuming the pool. This allows the algaecide to work effectively and kill the algae before you disturb it. Vacuuming too soon may reduce the efficacy of the treatment and could stir up dead algae, making the water cloudy. Always follow the specific instructions on the algaecide product for the best results.

Does algaecide remove mold from concrete?

Algaecide is primarily designed to kill algae and prevent its growth, not specifically to remove mold from concrete. While it may help in controlling some fungal growth, it is not effective against mold. To remove mold from concrete, a mildew remover or a mixture of bleach and water is typically more effective. Always ensure proper safety precautions when using chemicals for mold removal.
