Black Algae & Balancing

So, do I now let the chlorine level drift back down? And quit running the pumps 24/7?

Could you provide test results please? Did you perform the OCLT which confirms the end of a SLAM?

Yes, did an OCLT last week ~ results were 0.5. FC down to 9 today so I ran the full test.
FC 9
CC 0
TC 9
pH 8.2
CH 225
TA 120
CYA 60

Thanks. Reduce your pH down into the mid-sevens sooner rather than later. Always keep your pH no higher than 7.8 and reduce immediately every time it climbs above 8.

You might find it easier to slow the rate of increase if you will reduce your TA to around 60. There is an article in Pool School to tell you how.

Yes, heading to get acid today ~ used all I had before I started the SLAM. Will definitely check out the article ~ the pH climbs pretty quickly, always has.
