After receiving questionable advice from neighborhood pool store, I started balancing water chemistry and treating my pool for black algae the TFP way on Saturday. We have thousands of black spots on the bottom of the pool. We brushed spots on Saturday with metal brush and saw green plumes of algae float off. We are keeping FC between 10-15. Most of the black spots are fading to grayish now and we see small gray plumes when we brush.
Questions I have are:
Should we keep pump running 24/7 through this process?
When should we backwash?
Should I shampoo my filter with 'strip Kwik' as pool store recommended?
Am I damaging my pool surface with the metal brush?
