I am grateful for finding TFP, and just in time: we just fired our pool guy and I have hired myself to replace him. This will test my theory that diligence is as important as expertise, that being out there every day is the most important asset to pool maintenance.
Our pool is lightly used and I would prefer to under-chlorinate than over-chlorinate. I can live with a minimal amount of algae. I don't mind brushing the walls; in fact, I kind of enjoy it. When I brush algae from the walls of the pool, where does it go? Can algae live in the water? When I scrub it off of a wall, does it die or does it just go find another wall to cling to?
I don't want to mistreat my pool, and if I discover that I'm just spinning my wheels when brushing the walls, perhaps I'll reconsider. And of course, the best would be to maintain perfect chemical conditions, but that will require a lot of practice and (hopefully) the help of people here.
So that's my first question of many: is wall scrubbing in and of itself a defense against algae?
