Hello everyone,
Ive recently emptied the Nature2 Duo Cartridge, as recommended by many here on TFP. Just added 2lbs of shock & 8lbs of CYA, as I didnt have any chlorine. I've been getting brown/black spots on the plaster surface, which I'm guessing is black algae. I scrubbed with a 3" chlorine tab and they have gone away previously, but found 4 more spots today while brushing the pool. So I'll be diving down to scrub those too. Not the greatest picture but its the only one I have on this computer
