I test my pool daily using the cheap test kit that is pretty standard. I test PH and chlorine and keep it at normal levels. This is a plaster pool. I have been using liquid muriatic acid and liquid swimming pool chlorine. Probably brush the pool too often lol. Anyways, I notice small, less than dime size patches of I assume algae on the shady parts of the pool. It's not a lot, probably 10-15 of them for the whole pool. Pool is literally crystal clear, shimmering, etc, nice looking pool.
I assume the course I need to take at this point is SLAMMING the pool. Also I intend to switch to regular bleach from Target or wherever based on this forum.
