Really confused now.... brought fc up to 7ish this morning couldn't get actual reading before going to work.. got home from work today with no one in the pool today and had more stuff on bottom.... vac to waste.. tested water with results of FC 5.8 and CC at 0.2? Water itself is very clear and not losing fc?? However.... I did find an algae source in the pool that has been looked over (probably a newbie move) ..... the pockets on the back side of the ladder and inside the bottom step...Yuck... I assume this may be part of the problem? I took the ladder out and cleaned with straight 12.5% and toothbrush. Is there any way to keep back side of ladder clean with use of toothbrsh, or now that I have cleaned it the way I did I shouldn't have a problem?

Questions questions questions...

Thanks!
