I had the same type of thing happen on my pool. Well, mine wasn't as bad as yours sounds. I kept logs but the pool builder said it was my poor maintenance. I had kept everything in a spreadsheet because I didn't want to keep 10 years of monthly test results. But of course, the pool is never...

Interestingly, there has been some new studies that CYA is best at no higher than 50. In public pools, especially indoor pools, new recommendations are as low as 20! I'm actually coming around to the idea of keeping my CYA level at about 50-60 this summer instead of the usual 75-85...

I have a type of sandstone on my pool with a SWG. I've had it for about 6 years. It tooks me a while to figure out why my stone was getting so bad (although I do like the look of it in many areas where there is damage because it looks more natural). I did finally find a decent sealer...

Thanks for the advice. Honestly, it didn't occur to me to ask them what ranges they will be using for balance (I mean you have a lot going on with a remodel). Now I'll make sure to ask if they stick to NPC guidelines for startups. The monthly pool service isn't that helpful to me. NPC...

well, after talking to my original pool builder, my pool equipment maintenance guy, and doing some research on this forum (and elsewhere), I decided to spend the extra money to go with Pebble Tec. Virtually every response was to spend more money just because of the customer service of Pebble...

Re: Water Balance for SWGs Yeah, I'm not absolutely certain about pebble-tec's warranty but their website recommends using the langlier index. It provides ranges for TA, CH, and PH but not Chlorine. The stonescapes warranty does list these ranges and says anything above 4.0 is corrosive...

I've gotten two quotes for a remodel. Stonescapes came in a couple grand cheaper. Is Pebble Tec worth the extra money? Frankly, I don't like the colors. I want a darker blue but they all appear light blue or black to me.

Salt seems low at 2600. I have a Jandy system and that will not produce chlorine very well at that level. If I think the SWG isn't generating chlorine, I test the water out of the return directly. It should test substantially higher than the pool water. I don't know about your generator...

So you are recommending that SWG with high CYA have an 4.0 to 5.0 chlorine level? Why don't the manufacturers specify this? And how do we maintain that ratio in view of the plaster/pebble tec warranties?

I picked 200 as the low end. The 230 result was maybe shades of blue. At 190 it changed from light pink to a bluish purple color. At 200 it changed to blue and remained blue (prior to 190 the sample would change colors but as it was swirled by the magnetic device it went back to pink). At...

Well, to clairfy the line around the pool (at the water line) doesn't fizz up. I haven't tried using MA on the line around my faucets either, but it may not be enough to fizz (I use CLR on the faucets). I pulled a teeny tiny sample of the wall of the pool. It did fizz up when I added a drop...

I have a 20K gallon negative edge pool. I can't seem to control what appears to me to be calcium deposits on the pool plaster. To me they look a lot like efflorescence. The pool is a SWG with ozonator. It is blue-black colored plaster (looks blue). The white calcium can be sanded off...

I'll post my test results tonight and my pool specifics. I struggle to keep my pool under 7.8 in the summer time because of the SWG and the negative edge. Nonetheless, I have crystalling deposits that form on the walls no matter the pool chemistry. However, now with the calcium very low, I've...

Ok, I've taken my water to three different stores and all report low calcium numbers ranging from 125 to 150. However, the home kit I'm using registers are about 250. I'm using the Blue Devil DPD test kit. My DPD test seems to be about 70 to 100 points higher than the pools stores...
