I have what I think is a scale problem. First let me give you a little recent history. The other day I noticed white specs along the floor of my pool pretty much throughout, at first I thought it might be sand since we did have some wind, and I vacuumed it up. After I started vacuuming it up I realized it appeared to be a white type of soft scale. I thought maybe I let my pH drift too high, but in reality I don't think I ever a let it approach 8, really I don't think it ever got past 7.8. Anyway I was careful to keep my pH in order and after I cleaned it up I thought the problem would be done. Today coming home from work I seen in the wading pool what appeared to be an excessive amount of the same scale. I seen it in the shallow wading pool and also on the steps coming into the wading pool. Also on the sitting benches on the deep end of the pool, which would probably be about 16 inches deep I see some scale there as well. As of right now I do not see any in the deep end or even in water that is three or 4 feet deep. I will attach some pictures, here are my latest test results I just took with my TF100 kit.
Ph in deep end (6') - 7.3
Ph in wading pool - 7.3
CC - .5
CH - 325
TA - 130
CYA - 65
Salt using K1766 Kit - 3200
Temp - 86
Only things I have added to the pool other than the salt when I installed AquaRite AQRT15, is 20 Baum Muratic acid and 8.25% Clorox. I have been meticulous about my water chemistry and the water is actually very very clear.
I have reduced the TA almost in half, but it has been hanging around 130 for quite some time. I think this is due to the fact of evaporation and I have to add water now and then. I use well water, which as a TA of around 300, and also calcium hardness of around 350. All my tests showed zero iron or metals. Metal tests from Pool store and Culligan.
I took some of the scale and captured in a glass, and added vinegar, it did not attack it right away but after a while it did disappear. When I try to grab the scale it pretty much just dissolves. I did taste it, and it did not taste at all like salt. Of course I was careful not to ingest any. Hopefully I provided you enough information to hopefully help me solve this problem. Do you think it has to do with the SWG? We did have the pool replastered, but that was back a few months ago. Open till this point, I have had perfect water.
