I was a bit worried about my CH being too low for my plaster in ground pool, so I ended up adding 16 pounds of Calcium Chloride and it brought my CH up to 270 now. Each 4 pounds brought it up about 30ppm. Should I get another 4 pounds to bring it up to 300-310 or is 270 sufficient now? Thanks!
P.S. What exactly does "calcium leaching" look like in the plaster? Is it just white spots or does the plaster actually degrade? Googled it, but got a bunch of different pics, so I'm not sure now.
