30K Gal (30*20, average depth about 6.5) Plaster
Bleach (now, pucks before)
Taylor 2006 Kit (not 2005)
CC Less than 1
I was using some test strips before I found the light with this place and a good test kit, and either they were bad, I was colorblind, or something, but about six weeks ago I put in way too much CYA. 10 days ago drained about 40% of this thing and refilled (so CYA had to be above 200 at some point).
After the drain, I shocked it by TFP standards (Chlorine 45) and knocked out the algae.
Don't want to do a big drain again until the next water bill.
Algae is managed right now, pool is open and is in constant direct sunlight.
Is that CYA number going to continue to be an issue? How slowly is it going to decrease due to losing water to evaporation, etc.
Any advice for a pool like this and these numbers outside of pool school would be very appreciated.
