This is my 1st season w/TFP. We are the original owners of our pool. Prior to this spring, all of our water testing and chemicals were purchased via the local pool store. Our favorite pool store went "belly up" 4 or 5 years ago and since then, I've been ping ponging between two other local pool stores for our water tests and chemical purchases. Their test results were always wildly different between stores and even from within the same store. Needless to say, I started to sense a slow decline in the quality of my pool water during the past couple of years. At the close of last season, I started to see evidence of "pink" slime. This spring, although I opened the pool to a carpet of green algae and clear top water, I saw no visual evidence of the pink stuff.
After a couple of trips to the pool stores and getting wildly inconsistent test results, I decided I had had enough. Discovered the TFP site and began the processing of taking back control of my pool (and it feels soooo refreshing!)
Back in May, my pool was clean from debris, but the deep end remained cloudy.
Read about slamming, bought both TF-100 and Lamotte Pro 7 test kits and began slamming on 5/31
FC: 1.5 FC: 13.5
CC: 2.0 CC: 0.5
PH: 7.5 PH: 7.3 (taken a few days ago when FC=7)
TA: 100 TA: n/a
CH: 275 CH: n/a
CYA: 27ish CYA: 27ish (confirmed by both TF100 & Lamotte)
CYA years ago was 125+ but drop after draining/replacing 35% of my pool water. Thanks to TFP, I now understand the important relationships between CYA and FC.
Six days into my slam, the pool turned around and has been clear since then. Overnight FC loss now seems to be about 2ppms
My average daily FC seems to be around 8ppm since day one.
I suspect my Hayward inline chlorinator (w/TriChlor tabs) is faulty as the sun ravages my daytime FC levels.
My frustration is that at day 13, I still can't seem to get the CCs to zero. According to the pool calc my target shock level is 12ppm.
I feel I'm at 3rd base and just quite can get to home plate.
Any advice about how to best get the cc's down to zero would be greatly appreciated.
