Yes. We had a problem with algae one year. The chemical that kills the algae will eat up your chlorine until everything in the pool is dead. When you add the algaecide, you should add chlorine at the same time, imediately after. Your filter should be running 24 hours/day until the algae is clear. Everynight after the initial treatment, check your chlorine levels with an at-home test. They will likely be low. Add liquid chlorine if the levels are low. (You are not going to kill your liner since the levels are already low.) This aids in the algae killing process. You should only have to do this for a few nights. After the third or fourth night, if the algae seems to have cleared up, but the chlorine is still low, you may need to add stablizer, along with one more dose of liquid chlorine. It would be good to take a water sample to a pool chemical dealer after the algae appears cleared. The amount of liquid chlorine you add each night depends on the size of your pool and how low the chlorine levels.
Yes you can add shock solution to your swimming pool after or at the same time as a clarifyer. You should not swim in your pool for at 4 hours after shocking it.
Yes, you can add chlorine granules and algecide.
Yes, some pool shocks are sold with algecide.
A filter. Or you could take the leaves and stuff out. It might just be the reflection from the trees. If you think its really bad, you should drain the pool, wash the inside, then fill it with clean water. I say add algecide after scrubbing sides and bottom of pool while pump running after that get all levels of pool to normal if still green repeat algecide 48 hours later and vacuum.
Do not use blue (copper) algecide. If you have already added too much blue algecide in the past, the only way to remove it is to buy a metal remover at your pool supply or do a partial drain and refill of the pool water. Pool Masters
Yes, you should run the pump when you add chemicals to your water,
go buy an algecide specificly meant for black algae from a pool/spa store.
Shocking a pool with products like chlorine can actually lower the pH and alkalinity levels of the pool water temporarily. It is recommended to test the water and adjust the alkalinity levels if necessary after shocking the pool to maintain proper water balance.
It's generally not recommended to add algaecide to a pool on the same day that you shock it. Shocking the pool raises the chlorine levels significantly, which can reduce the effectiveness of the algaecide. It's best to wait at least 24 hours after shocking to allow the chlorine levels to drop before adding algaecide for optimal results. Always check the product labels for specific instructions.
Algae can appear at the bottom of a pool after shocking it because the shock treatment can kill off algae and other organic matter, causing it to sink to the bottom.
Try algecide gel and a soft sponge. You might also try Vitamin C tablets in a sock.
Pretty much --Yes.
