I just got my TF100 test set.
I have a minor black algae problem and started this morning doing the SLAM routine to get rid of it.
Everything is going fine. I brushed with a steel brush (twice) and have kept at shock level all day. The algae is disappearing.
I just did a CH test. It was so high I did it twice. It's at 1,100. My tap water is at 90.
I guess that's from years of using chlorine tabs and Leslie's powder shock.
I have a lime/calcium residue on the dark blue tile around the water level. I can acid scrub it off without too much trouble.
I hate to drain the pool, but it looks like I might have to.
Any suggestions?
