Copper Power (Endich) ACP0124B Blue Salt Water Gallon

best and safest copper treatment i have ever used ,saved my fish

For blue-green or black algae, copper based algaecides are the only thing that work. For other lessor algae foes in your pool like yellow mustard algae, this might not be the product to start with, as it does have some potential downsides. I used this product at 1tablespoon per thousand gallons dissolved in warm water and added it to my pool after balancing pH, total alkalinity, and chlorine levels. After 24 hours, I brushed the pool floor and walls, and rinsed the filter. It was starting to get plugged with dead algae. Then I repeated the brushing and rinsing of the filter after a couple days. The algae was almost gone. Depending on the severity of your algae problem, it may take a few days or more than a week to get it all knocked down. Just remember too much copper in your pool will stain the plaster blue or even grey forever. The dissolved copper doesn’t evaporate or dissipate, so don’t add more than the recommended amounts. Remember, go slow, have patience and don’t overdo it. Does the same thing as the copper based algae killers in the pool store for much less.

This is the most effective product on the market.
