Currently getting my water tested at the pool store. I will soon be purchasing a good test kit and start doing things myself instead of burning up my checking account at the pool store. I'm tired of adding chemicals, and then adding more chemicals to correct the additional problems caused by what else..but chemicals. Ugh.

Pool has been super cloudy but is getting better slowly.

Current readings from today:

FC: 0
TC: 0
CC: 0
(ODD because I just installed a new chlorinator and though have had issues, it is now eroding tablets. Over the past week, I have added 12 pounds of granular chlorine, on top of multiple additions of Breakout 35, all to no avail) They want me to add an additional 8 cups of breakout 35 tonight.

pH 6.3 (also odd because up until today it has been in normal range)
Hardness 191
Alk 90.5 ( I just added 6lb alkalinity up and will retest tomorrow morning)
CYA 95
TDS 1751

I have already drained 25% and replaced.

My pool is ~12,000 gallons, gunite with auto cover. Pentair superflo single speed pump, hayward cartridge filter, rainbow 320 inline chlorinator in top feed configuration. I just switched it to top feed because it wasn't holding water or dissolving my tablets in bottom feed configuration. Even now, there is minimal water that stays in the chamber.

I do have a heater, but it is currently not turned on. Saving money since no one is swimming anyhow.

Can anyone give me some pointers on how to fix this without spending an additional $500 on chemicals that seem to cause more harm than good?
