I'm new here and so far I was mostly reading and learning. Thank you for this amazing knowledge base!
I have been struggling with my pool recently and slowly giving up. As far as I can tell the water is balanced ok but the pool is cloudy ( I can just see the bottom but barely) and I occasionally had some green alge on the walls. The pool has been cloudy for a few weeks now. I was monitoring FC levels and it was always at least above 3.
I have been testing water in a local pool shop and following their advice. I think the pool got cloudy after I bumped TA to the current level (they recommend 100-150). I have also been using phosphate remover a few times without much success. The pool is surrounded by trees so there is always something in it. In last few weeks I tried to run pump more, used some blue jelly that is supposed to clear water and worked for me in the past but progressively the pool looks worse and worse. I can see two options now:
1. shock it. not sure if its is going to help as it seems that there is no CF in the water.
2. flock it? I don't really like flocking as it requires vacuuming to drain which wastes chemicals and water.
it is a concrete (old) salt water pool and I'm located in Sydney. the water temperature is around 23 celsius.
