    Is this algae (Pic)? Keeps coming back, even though chemistry is balanced...

    I recently went through the SLAM process and my water is now crystal clear and chemicals stay balanced. There is 0 CC, and does not come back up between days. The odd thing, is I am finding this sort of stringy looking green algae in the skimmer basket on a daily basis: Nothing else around...

    FC Test question about turning pink with K-2006 kit

    I am in the process of a SLAM and my FC test is doing something I've not experienced before. I add the powder, water turns pink (10ml). As I add drops of R-0871 it starts to clear up, but after a few drops, the water may go clear while I'm swirling, but goes back to just barely pink if I let...

    Does SLAMing really use this much chlorine?

Yet I still find pretty drastic drops in FC, for example last night at 9:30pm I topped it back off to being 14, checked again today around 1pm and...

    I am backwashing for the first time. I have a Hayward Pro-Grid DE2420 filter. On the sticker it says I will need to add 3lbs of DE. So I've run the pump on backwash for a few minutes and my water doesn't seem to get clearer than this: I've tried going back to rinse, and then back to...

    New pool owner, chlorine CC and FC too high, what to do?

    I just purchased my home in November, it had a in-ground pool, and it's my first time having a pool. We had it professionally opened a few weeks ago. Yesterday we had a couple friends over for the first time, all the girls noticed a burning/itching sensation, mostly on their legs. The two...
