lalittle: I have had my own battles with the acid dragon over the last 18+ months since my install. One thing that seems to have helped is increasing my CYA. My finish installer gave me suggested chemical ranges that were pretty close to what the Taylor kit recommends. The one big difference...

I met with the Pebble Tec rep and he could not confirm if calcium chloride was used. He said they are allowed up to 2% calcuim. As I suspected, he would not address the fact that I wasn't concerned how much was used, but rather IF it was used. He said they (the installer) couldn't have used much...

onBalance - Thank you for taking the time to review this thread and give me your opinion of what is going on with my pool. This is not good news for me, but I understand what you are saying about not being able to rectify it. However, doesn't the builder or the pool finish company bear some...

duraleigh - I used Oceancare Calcium Releaser, an NTP product. My pool builder gave it to me to try. I have used muriatic acid sparingly...I was afraid it might harm the grout. Both required way more elbow grease than I was willing to put into it. The pressure washer was a little better...

Please look to the right of the spillover to see calcium deposits. Am I wrong to call that scale? Here is a closer view of the same area: It is NOT easily removed. I tried a removal product and even a pressure washer that damaged the tile while trying to remove. The deposits along the...

Lux Man- The pool builder has seen it, and thinks it is scale. I also have what looks like calcium deposits on my glass tiles at the waterline and on the side of the spa. Would that still lead you to believe efflorescence, or does it sound more like scale?

Seems like a lot of hoops to post a few pics, but here goes: Test results from today, Saturday 2-15-2015@11:15am: Air Temp: 66 Pool Temp: 56 Salt: 2400 ppm (need to add two bags) SWG: 20% Filter: 20 psi FC 4.5 (from TFP kit) CC 0 pH 7.8; reduced to 7.6 w/ 1 drop of #5 Acid Demand...

My pool builder did take care of the pool during break in, but I'm pretty sure that we did not follow the procedure outlined here (TFP). We were swimming pretty quickly after it was filled. I do know they waited a couple of weeks to add the salt. The pool was acid washed in spring (March...

Thanks everyone. Sorry for the delay in response. We had internet issues at the house for a few days. The pool finish is Pebble Tec Black Pearl. This is one color scale away from their darkest color (Jet Black, I believe). The scale looks like patches of grey dust on the pool surface. It...

When I started the pool in June 2013, I balanced the water using the Taylor book in my kit. The big difference with the TFP recommendations was Taylor uses lower stabilizer: 30-50. At that lower cyn level, and water temps in the 86-92 degree range, I was seeing an increase in pH levels of 0.2...

First time posting, so here goes. I did do some research and found a lot of great info (Thanks!), but not an answer to my specific questions/issues. My pool has had high acid demand (up to 2 gallons per week) and scaling issues since it was new. Adding that much acid would crush my...
