Just curious about this one.....
Everything was balanced when I closed, but I will admit to throwing a bunch of bleach in pretty close to closure, so I suppose that could have driven ph up.
Just opened, pool looks nice, I played around and I'm almost balanced:
ph 8.2 originally, 1.5 bottle of muriatic later and I'm back to normal -7.6
CYA - was around 60 when closed, but I'm our of R-013. Pool store reports 40 so take it with a grain of salt.
Salt - 2500 low....need to add to get to 3200
I have what appears to be calcium deposits on the walls....very white sand-like. I've brushed the walls pretty well and my cleaner does a good job of cleaning up until it's weighed down like a stone with these little bits. I have 2 main concerns:
- Did I do something wrong? I was balanced at closing (admittedly on the low end of the CH recommendation) What is the recommendation for next time? This is the third season for the pool in case this is normal.
- What are the allowed ways for me to remove these bits? Fingernails work mostly, but that will be just a bit time consuming. The nylon brush isn't cutting it. I would think pumice stone would be too soft. How about a hard piece of plastic? I'm game as long as it doesn't hurt the plaster.
Looking forward to hearing the answers....thanks in advance!
