I have almost had my pool for a year now, when I first started my CYA was around 80...high but manageable. My CYA is currently 140 and I have been battling to keep the algae out. From everything I have read, it is because of the trichlor pucks that I use as my main source of chlorine. Looking at switching to bleach using the BBB so that i don't drive my CYA up, but how often will I have to add it, how much (loaded question, depends)? I am wondering what the average person is doing out there.
I have never drained a pool before, and I want to know how. I will post a picture of my pool equipment so that someone can help me figure out what valves to move. I'm guessing I just need to turn the suction off the skimmers (but how) and then I can turn the multi-port valve to dump from there. If anyone can label the valves I didn't so that I know what they do that would help. I had a local pool guy out, and he wasn't very helpful...just told me that he dodn't know why they put so many useless valves in
