I had to start a shocking process recently bc we had been out of town and the chlorine went to zero, so it's coming down at a rate of about 1ppm in my OCLT's and the pool water does look clear. Suggestions on what to do about pool maintenance when out of town would be greatly appreciated...should we increase the chlorine by 1ppm for the days that we will be gone so that when we come home it's where it should be??
I don't know what to do about our CH though. We live in a very hard water area in a suburb of Austin, TX where we basically must use a salt water softner for our home...so my thoughts were that draining the pool down to replace it with new water as a solution didn't make sense to me b/c I'd just be replacing hard water with even harder water....so, I did a chemistry test on our outside faucet water where we would be replacing water from. The test came back with CH of 160. Just to compare, I also tested an inside faucet that is run through our water softner and the water did not turn pink, but rather purple and just to see what it would take to turn it to blue ended up at 120.
So.....are my thoughts basically incorrect? Dilution IS the solution??
The calcium scaling on our flagstone beach entry and some of the coping is starting to get really bad, so I want to address it ASAP.
Suggestions on how to clean up this scaling in the grout would be great too. We've tried just about everything and I can't clean it off.
