I was able to dive down and take a look today, still working a lot. Anyhow, I don’t think it’s algae. Pretty sure my pebbletec is failing. Then googling I actually think I may have pebble sheen. But with that said, if it’s flaking and I can see small pits, anyone know an average cost to...

Haven’t been able to do the vitamin test or cal-hypo yet, but I’ll try this weekend. Here’s some current pictures. I’m beginning to think it’s the pebble tech

ok cool, so you mean dive down and do these tests? for the Cal-hypo, I shouldn't just sprinkle it across the pool then. Just target that spot.

How would I perform these tests? Do I need to drain it to apply the Vitamin C, or just dive down and try to rub it on there? Or are you just recommending for the cal-hypo to just add it like a normal shock?

Hello all, here's an update. I've been baby sitting his thing since my last post on Friday. I've kept my Chlorine levels around 8-10, black spot's are slightly lighter but it could be in my head. I am losing about .5ppm of chlorine a day, not sure if that's still meaning I need to keep my level...

Thanks for the reply. I’m running the pump all night again and decided to raise my chlorine level based on that chart. I’ll test it again after 24 hours and see how things look and where my chemistry is.

sorry for the late reply, here's a test from just now. FC = 7 CYA = 70 PH 7.4 TA = 120 CH = 250 Salt = 3100 Temp = 92 based on your chart Kellyfair I do need to raise my FC.

no algaecide or anything like that. Thanks for the articles, I'll read through them.

I'm at work now, but I will post a results when I get home later this afternoon. So far, it's been pretty normal. FCL is about 3, pH(normal battle and try to keep it here) but around 7.4-7.6, CH is around 250, don't recall TA, but I don't think it was high. Anyhow I'll get you some numbers...

Hello All, I've attached some images, which were the best shots I could get of these black areas on my pool walls. I noticed this just last week, and I've been traveling a lot so it could have been there sooner. So Sunday, I tried the normal got my brush and quickly saw nothing was coming off...

I have recently found that I'm losing water at my skimmers. Basically where the wall tiles meet up at the skimmer. I've been researching what grout or caulk I should use to fix this, since I'm losing water there. Any recommendations?
