Hi! I've discovered this website a week or two ago, and have spent a lot of time reading through Pool School, learning to use the Pool Calculator, and so on. Very good resource, especially since I no longer trust my local pool store. They've given me a lot of bad advice lately....
Anyway, here's what is going on. A year ago, I had issues with copper in the water (staining, etc), and dumped $300 on chemicals to sequester the metal (Metal Free is all they offer at the local store), and on stain removers (Ascorbic Acid). Got the pool ok, but this year, the same issues recurred as I opened the pool. So - more stain removers, 3 jugs of metal free, etc. The pool has been flourescent green, blue, clear and then cloudy, in that order this year. I believe at this point I am fighting algae, but after dumping $50 bucks worth of chlorine into the water in the past 36 hours (liquid bleach, then switched to dichlor that I had on hand), I'm about ready to drain and refill the pool. Which may let me also work out a wrinkle that has developed in the vinyl liner, on the slope down to the deep end.
Anyway, here's the numbers I know right now:
FC - 0
CC - 2
pH - 7.2
TA - 140
CH - 50
CYA - 30
TDS - 500
I dumped 15 pounds of dichlor shock into the pool last night, brushed the pool, and when I got up this morning - FC was back to 0, CC was still 2, and water is still cloudy to where you cannot see the bottom of the deep end.
So guys (and gals) - do I do a partial refill (and fix my wrinkled liner), or keep throwing chlorine and money into the pool. Liner is 5 years old, in case that matters on the decision to drain/fill.
