my cya is now 64...........getting there 16 inches at a time. The copper is down from .4 to .2. Maybe my blonde won't turn quite so green anymore.
you have a vinyl pool, no need to add calcium. They only problem you can have with calcium in a vinyl pool is too much of the stuff. Don't add calcium.Never mind researching. I have already contacted the hazardous waste department at our sanitation service dept. They will pick up the material on 9/6. Not worth any risk. I will just purchase some fresh calcium. These
chemicals are exactly that......chemicals first and foremost. lyn
Sigh......@Tim ... you missed the mention of the fiberglass spa, as did I originally.
