    Cleaning cover before closing

    When I opened my pool at the beginning of the season, I had an algae problem which might have been mustard algae? I wasn't sure and just treated it that way with directions from this site. The water cleared up and the pool has been running clear all summer (Thanks TFP!). Now that I'm getting...

    Algae prevention

    So, back in July I went through a algae problem which I was able to successfully overcome through SLAM. However, since then, I feel like it comes back so easily even though I have been making sure to keep the chlorine over the recommended levels for my CYA and I feel like I am constantly running...

    Pool clear. 0.0-0.2 combined chlorine. Green hose.

    Hi! During a multi-day rainstorm, I couldn't keep the chlorine within range. So, we ended up with outflow hoses that are now yellow-green on the inside. My consistent, non-stormy pool maintenance keeps my combined clorine tests at 0.0-0.2, my free chlorine within range for my CYA, and slamming...

    Does anyone have one or both setup on their pools? I am looking for the ionizer to help prevent algae by raising copper levels (clear blue ionizer) then a UV lamp to also help treat the water as it passes through the system. I'm hoping this helps my sanitizer work more efficiently and can be...

    48 hrs into SLAM and the yellow in my plaster isn't disappearing

    Hi all. I started a SLAM 48+ hours ago because I noticed what I thought was yellow colored algae in various spots around the pool. It doesn't seem to be disappearing and I can't rub it away with my finger with vigorous scrubbing so could these spots be some sort of stain in the plaster? And if...
