Recurring Algae on Bottom of Pool

[aylad]

You might try putting all the "stuff" you use in the pool (floats, noodles, brushes, nets, etc) into the pool while it's shocked so that if there is algae growing on any of that stuff it will be killed and not re-introduced into the pool. Also check lighting sockets, ridges around pool steps, etc and make sure there's nothing hiding from you.

Well I finally got rid of the algae. 20 ppm bleach for 4 - 5 days won out. The liner still has light brown stains. Don't know what it is. I am going to keep it above 5 ppm from now on and hopefully it won't return.

Brown could be iron oxide or dead algae.
