I know it's not normally a waste but here in Colorado, we have about 3/4 weeks left of the pool. My CYA is down to zero (I'll get better at testing that one next year but seemed to go through a load of CYA test an thought it was kinda expensive for 3/4 tests per bottle) and the pool calculator tells me to add 8lbs to my 25k inground pool.
My question really is - If I put 8 lbs of CYA in ($30) to bring it up to 40, will it be gone by the time I re-open the pool next year or will it still be around?
This is my first year of having the pool so looking for some pre-closure tips.
Would my train of thought be - if I don't mind wasting a bit more bleach using BBB, then don't bother with it. Should I put half in, bearing in mind it will take a week to take effect/read or should I drop the whole amount in and will reap the benefits next spring?
thanks all again in advance. I've had a great summer in the pool thanks to you guys and the missus and kids have never been happier. Colorado weather could've been a little better but maybe next year...
(p.s. we tend not to get snow prior to mid/late october)
