Algae under pool steps

[les_smith]

I've got these steps and this year I drilled holes in the sides. Three, 3 inch holes on each side.

After drilling the holes the difference was very noticeable we have yet to see algae in them. Even while we were using Pristine Blue earlier this year we never saw algae in them. We angle our return to the side so it moves the water in a circle around the pool. If the algae is inside the stairs, like mine was, tbit his will definitely help. Now, having switched to BBB all I get in the stairs is a little of a brown residue that the filter won't catch. I just put my vacuum hose in there and it sucks it out.

We have Lumi-O steps and they already have several holes already drilled in each side. I do not recommend adding a puck in the steps as it can bleach your liner! Trust me on that Lumi-o had it listed as a recommendation in their instructions and that is why I did it. Steps also have a 2" hole in the top of the 2nd step for placing a hose when adding water to your pool. This I do recommend as it does circulate water through the steps. I do get debris that settles in the steps as someone mentioned but no algae. The two things that I do and so far have been successful with are; add 4 Oz's of poly 60 over my steps every Sunday and as often as possible before getting out of the pool I would around the perimeter for a couple laps to get a good old fashion whirlpool going. Not only does it circulate the water past the steps but it is great exercise as well
