Hi from Spring, TX! We moved to our current house about two years ago which already had (what we’ve been told is) a 50k gallon pool. We are on our third weekly pool maintenance company but we just noticed green algae last week. The pool company came to address it but it’s already starting to reappear. I have very much been wanting to learn how to maintain the pool myself, if for no other reason than to know whether the pool guys are staying on top of everything. So I’m glad to have found this forum. Hoping to be a little less befuddled soon!
