Hello All,
I've recently become the owner of a pool and I'm learning how to take care of it. With some help from other forum readers, I've determined that the CYA level is around 200 and I plan to drain a lot of water to get this down to 50 - 60. (In central Texas with a lot of sun in summer, maybe 60 is ok?)
First question is, how much can I safely drain before filling it back up? To go from CYA 200 to 50 I'd have to replace 75% of the water! Can I do that at once or is it better to do it in stages?
Second, can I drain it with my pool pump? I have 2 skimmers and drains in the bottom of the pool. Is it possible to disable the skimmers and use the bottom drains to remove so much water? There is a multiport valve but I don't really know how to use it. Is it safer to just buy/rent a submersible pump and use that instead?
Last question, assuming I remove 50% or more of the water it will take a long time to fill it back up w/ a single hose. While it's that low I can't run the filter, and I'm concerned it might turn green. Can I just add some liquid chlorine as it fills (to keep algae at bay), then get everything properly balanced once it's full again?
Thank you,
Colin
