Fantastic site. I belong to a similar one for lawn care. Love when good people get together to share good knowledge. I know I don't have my account set up properly yet but I've been lurking for a bit. I promise to become a law abiding member soon.
I just bought this house with 28K plaster pool with spa. Cartridge filter (I replaced filter media 4 weeks ago after I was quoted $800 - I did it for $120 and 20 minutes time) Full sun all day.
Water has been clear since I moved in and I've at least switched over to bleach and ordered the proper testing kit. I plan to do everything by the TFT book next year but want to make sure I handle the end of season here as well as I can.
So from what I've read, my main culprit right now is high CYA and therefor I'm low on FC. I've been adding about a gallon of bleach a week and again the water looks great. I have a company coming to close the pool on the 15th. They have some winterizing chems they will add that I'm sure I'm wasting a bit of money on but I'll learn and improve next year.
So what should I do in these next 10 days (I also want to be able to have the kids swim next weekend to end the season) I have some bags of Hypo-Cal that I bought before I found this site. I assume I can use those to semi-shock the pool and I can benefit from the increased CH. Is that right? What about the CYA - should I drain and refill now or just wait till spring and do it when opening?
Thanks in advance for any help. Happy Labor day to all!
