    Your black algae must be very deeply rooted, but that seems very odd with a painted pool. Usually, scraping off the waxy layer and exposing the deeper algae to chlorine is enough to kill it. We look forward to seeing how the Trichlor granular works though as you point out I'm not sure what you'll be able to do with the walls in that case.

    I think ours is a gunite construction, not painted concrete.

    OK, then you need to change your signature because it says "18x32 kidney 15K gal IG painted concrete pool". That's why I made that comment.

    I thought so too.. I changed the signature now. But I am sure I tried to change it a couple of times few months ago, but it was not saving my signature for some reason then, but I was able to this time.. weird
