Sorry for not being able to post my test results, but I'm on lunch at work. Maybe tonight...
My CYA level is at the 95 level right as of this morning. I've been draining water the past four days by using the floor drain only and connecting a vinyl tube to the air release valve and releasing it into the street. I assume that this isn't great for the cartridge filter, but I don't see any other options (besides renting a pump from Home Depot). Didn't want the water level to go below the return jets in fear of what could happen, so I've been draining about ten inches at a time and refilling at night and doing it all over again the next day.
My question is what would you do in my situation? Rent the pump from HD for $25 and do about a 50% drain? Or try to maintain appropriate FC levels for my current CYA reading and keep this draining process going until eventually I'm down to the 50 CYA range?
I am terrified of my plaster cracking or the pool floating out of the ground due to ground water issues if I drain 50%. Am I at any risk of cracking or floating if it hasn't rained in a week or so and it's been in the 90s and sunny consistently all week? I live in the Dallas, TX area.
Appreciate the help in advance. I'm in the process of switching to the BBB Method from using pucks and chlor-brite as shock (yes, I know I know). Bought 15 bottles of Chlorox Reg bleach last night. Anyone know of the cheapest option in this area for 12.5% liquid chlorine or bleach? Home Depot sells some "Smart" brand at 11% available chlorine for $4.5 / gallon.
Have a good day.
