    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

    Welcome Ryan!

    Great looking pool!
    Black Algae is the worst of the worst if thats what it is. Nothing short of scrubbing and scrubbing and scrubbing it and keeping your FC levels elevated will eradicate it.

    Enjoy TFP!

    A good test kit is an investment, not an expense.
