I know this post isn't going to follow the guidelines at the sticky of the thread, and this is because the pool in question isn't my own and right now I don't know anything about it, besides the fact its 30-35,000 gallons and has cartridge filters. I'm in an awkward situation where a friend of the family helped us out with our trees so somehow I got volunteered to take care of his pool, only because ours is "clear" and "nice" honestly I have no idea what I'm doing I'm just good at maintaining it, have been the last few years, but we have never really had major problems it’s easy to maintain something that doesn’t have problems.
With that said, I don't know anything about the pool except that it’s extremely green with algae; the water itself has turned a green color. I know that last year he spent over 1600 dollars in materials for the pool to get it nice and clean (which he did) but then there was a horrible tornado in our town which made it worse, and he hasn't touched it since.
I know he’s going to call me up soon for help. I just need to know some articles, or posts about what to do when the pool is completely green. I'm sure that no matter what type of pool it is the fundementals are all the same. I assume the first step is to clean up, kill, and get rid of the algae, but I don't even know how to go about doing that. Never had algae problems in our pool in 20 years, and not in the last few years I’ve been maintaining it.
Any help would be greatly appreciated.
