We did a complete drain/fill this weekend (refilled pool on Monday) and my wife says the pool guy that helped me out dumped a bucket of CYA into the Filter Cartridge housing and sealed it up. This was a 5 gallon bucket of detergent looking CYA. I wasn't home during this to stop him. It's only been 4 days since the fill and I have checked the CYA levels daily and they are completely off the charts and over 200. Could this be because I am checking the level way too soon? I am completely obsessed with my chemical levels since finding this site a couple weeks ago I WANT IT RIGHT NOW!!! haha. I just really need to know if it's too soon to tell or should I take the filters apart and get the CYA out of the cartridge housing he dumped in. The pressure seems fine but I worry because I read that this doesn't dissolve property. I'm in a small panic!!! I have a SWG that is currently off and I put liquid chlorine in because the pool was filled from a hydrant and water was green. My CYA is over 200 it seems and my FC is 18, PH is 7.5, TA is 175, CH 200. Water looks fine.
