Just need some expert opinions on my water chemistry. I think I'm in good shape, but want a perfect pool for tomorrow's festivities. Appreciate your help! FC-5.0 CC-.5 TA-70 CH-330 CYA-60-70 range Borates 30 With evaporation and rain, my CYA will naturally come down so I'm not too concerned...

There a couple of spots on the wall of my pool that gets direct sunlight for a good portion of the day, and I'm noticing some green tint in the grout, but it's above the water level line. How do I manage this and keep it from spreading into the pool? That's the only green the pool's seen in 6...

Six months into the TFP method, a few struggles here and there with CYA and TA, but I think I'm getting to cruise control levels. Tell me what you think: FC: 3.9 CC: .5 pH: 7.6 TA: 70 (down from 130) CA: 230 CYA: 20 My CYA used to be well over 200, but with water replacement and several big...

Simple question...what do you all use to measure and pour your liquid chlorine? My chlorine comes in refillable 2.5 gallon jugs, so if I need to add 58 oz. (or whatever) what's the best and easiest way? Are there large measuring cups I don't know about?

For the last 3 days I've been using the testing agents in my K-2006 kit that I found on Craigslist. Well, today the mailman brought me a package with some new reagents. Specifically, all three bottles to test TA. I wanted to be shown that I needed these new chems and that I didn't waste my...

Bought my house in October of last year and it came with a pool. I'm from Chicago area, so I knew nothing about maintaining a pool. Luckily I found this site rather quickly and didn't get pool stored (or however you phrase it). Long story, short...once I got the green cesspool looking like...

So I just got a new container of R-0870 and R-0871 from tftestkits. Before then, the pool store told me my FC level was at 5 (now I know that's as high as it goes for them). So I was excited to do a proper test and get accurate results. I filled the vial up to the 10mm mark, put in 2 dippers...

I calculate that my CYA is over 200 using the black dot method and using half tap water/doubling results. According to the (you all are right, they don't know much) pool store, my FC and TC is at 5-6. Clearly I need to add chlorine. My question is, should I be adding it while I'm doing the...
