Another day, another random thought...... We've heard stories and seen evidence of people's CYA disappearing over the winter, and I think I remember reading that it was due to some sort of bacteria eating the CYA. Is there anymore known about this? What if...someone could identify the...

Sitting around this morning killing time reading through the posts and a idea popped into my head - (brain cramp)... So many people get confused by the term "shock" when dealing with pools, the old "product" vs. "process" concept. I think we should adopt some new term to call the "process"...

Hi All, Second season with the pool. Last year went well, learned a lot here and didn't have any major problems. This year, I'm considering adding Borates to improve the swimming "experience", but have few questions: I live in the Dallas area and the fill water TA is normally 110 to 120...

I've got old Intermatic mechanical timers for my pool pump and booster pump(220V). Recently, I've noticed that there is an arc behind the pool pump timer whenever the switch is turned on. I'm not sure if it's always been like that or if it is something new. Either way, I'm going to do...

In my quest to understand how my Compupool CPSC48 works, and to try to understand why I periodically get the high salt indication, I decided to run a little test. Tech support sent the calibration instructions, and the told me to set the polarity numbers to -18. The calibration instructions...

Hi, I've noticed that over the last few weeks, the scaling in my pool seems to be dissolving slowly. If I rub the scaled areas, a little cloud comes off, and when I brush, it does the same thing. Here's my recent numbers: FC 5 CC 0 pH 7.6 TA 120 CH 400 CYA 80 Salt 3330 Water temp 88 CSI...

Hello Everyone, I installed a CPSC48 about a month ago, and like many here, get an occasional high salt light. The unit still produces, but I get the light. According to the test strip, the salt is 2860 PPM which is on the low end, and the efficiency suffers. I called Compupool a while ago...

I was just sitting at work, reading the boards with nothing better to do and I got to thinking....... When the ph gets high in my pool (7.8 to 8.0), i get white flakes on the SWG cell and they flake off when the cell reverses polarity. From what I have read, the flakes are primarily calcium...

I bought a house with an old Legend cleaner. The hose looks like part of it was replaced at some time. One section of hose has new looking floats that are smooth, and another section has old looking floats that are pitted. Almost like a sacrificial anode of sorts. When I rub the pitted...

Quick question: Is there a specific "type" of vitamin c tablet I should use to test stains? I haven't bought vitamin c in years so I asked my wife to pick up some today. She got some chewable ones. I wonder if they are too weak or might have other issues being chewable? Thanks in advance, Rob

Hello Experts! I have a new SWG on the way (Compupool CPSC48) as well as two new Jandy Neverlube valves to replace the Pool and spa return ball valves shown in the picture. Normally, the spa overflows into the pool. 25k gallon pool. My question is whether I should install the cell in...

Hi Everyone, I just bought a new house with a pool, first pool I've ever owned. The previous owner used a chemical service, and apparently they came once a week. From what I can tell, they basically add CYA twice per year, and liquid chlorine every week. All that for $50 per month - what a...
