At least a rule I live by anyway…if the water is hazy, dull, or you can’t see the bottom of the pool, your pool chemistry may be unbalanced. That’s not to say there may be issues with your filter as well. We will discuss those in the future. The best course of action at this point is to adjust those chems before you jump in. To turn things around as quickly as possible, add chlorine to the water. Liquid, tablets, powder, the choice is yours. You want to sanitize the water. 1.5- 3.0 ppm is a good rule of thumb for the amount of sanitizer that needs to be present in your pool. For the best results, you want to run your pool pump as much as possible to filter the water as it clears up. Not to be forgotten are alkalinity and pH. Of course there are many parameters that need to be considered, but first let’s get that water clear!
