I'm new to this forum so I'll try to make this as easy as possible. I have a 30' round above ground pool with a sand filter and swg. This is our 4th summer with this pool and the first year I've had any problems. We have no trees in the area so during winter we just drain past the plumbing and refill the next year. Every other year our filter has had the water clear in 3 days and all that's left is balancing. This year the water never cleared. It is a beautiful shade of aqua blue but u can barely see the second step on the stairs. There is also serious scale build up on everything and u can see particles in the water. Also had at least an inch thick layer of algae on the bottom. In the beginning water balance was spot on. We've tried clarifier first, then extremely low ph and high chlorine, still nothing so then vacuumed out all algae (still not being able to see what I'm walking in) then used algaecide and flocculant. Still nothing although I'm no longer getting clouds of brown nastiness when I brush. I have no idea what's going on. Tried getting help from hth and our local pool store. Everyone has different ideas but nothing is working. Please help.
This morning's test results: (using test strips so I'll try to be as accurate as I can get with these numbers)
Fc:8 (i did just shock)
Cya:30 maybe lower
Please note we were running alkalinity low in preparation for adding borates from a previous post on this forum that I was really excited to try this year
