Our problem first started with not getting the pool covered for winter ( western PA ). The in ground pool lines were winterized. The pool is 20' X 40'.
Second problem occurred when the pool pump failed.... so no filtration until just a week ago.
The algae growth is just unreal at this point !
I did contact a chemical company that has a 15% concentration of sodium hypochlorite.
Is this too much for shocking the pool ?
What harmful affects may this present?
We were applying a 10 parts per million to solve this problem.
Any advise is greatly appreciated.
