We purchased a home and are moving in tomorrow. I was able to go over and test the pool last night. Using a clorox strip everything was off the charts high for the most part. I then tried out my new K-2006 test kit testing only the FC. I lost track of the drops using the 25ml method and then tried again using the 10ml method. Once I got past 10ppm I just quit thinking the pool might be in shock. The kids actually jumped in for a few minutes while I was testing.
Today I went back for a full test.
FC - 18ppm
CC - 0ppm
pH - 7.6
Alk - between 175 and 200
CH - After 7 drops it went from red to clear but never turned blue. This calculated to about 175. Should I have kept adding more drops to wait for it to turn from clear to blue? Is there something else I need to do to get this test to work better? Maybe more indicator drops?
CYA - First pass was off the scale above 100. I diluted it 3x with distilled water and got a reading between 80 and 90. If I assume around 85 then we are at 255 on CYA.
Pool math says FC needs to be between 19 and 29 when CYA is this high. My CYA dilutions may not have been exactly accurate. The pool is currently being chlorinated by some tablets but I don't know what kind or how to know what kind. I was thinking of letting those finish out and then start using only liquid chlorine.
My first question. Does the CYA calculator really work at those high levels? Is the pool safe to swim at FC 18? The water looks perfect. The kids are going to want to swim on our first day in the new house. I know I need to start working on getting CYA down by draining and refilling. I need to research where to get the right pump for this. Does anyone have experience with swimming in pools with FC over 18 and CYA in the 200-300 range? I am also struggling to calculate the gallons for this pool. The shape is irregular, but I estimate somewhere around 16,500 to 17,000.
Any comments or advice is greatly appreciated.
