Our pool is very old, over thirty years. It’s an above ground, 30,000 gallon, vinyl lining pool. Usually we just take our water into Ace Hardware, or a pool supply store in our little and get it tested and then follow the instructions. Usually our pool for opening it for the year is alright. Maybe a little PH minus or Plus here and there, but spot on most of the time. This year however our hardness is apparently 0ppm. We were told we needed 105 pounds of Calcium Plus to fix the problem. I do believe this is correct because we just started getting some yellow stains on our liner that we never had before, and I heard low hardness can do this.
The problem is 105 pounds. That is a lot, over 150 dollars for the cheapest we can find (online we found you can get a 25 pound bucket for 22 dollar, but with 20 dollars shipping we might as well buy it in the store for 45 dollars).
Is it really safe to just dump 105 pounds of this in there? I know we are supposed to do in over the course of 3-5 days, doing about 1/5 of the needed amount each day. But I just wanted to know the proper procedure.
After putting this much Calcium Plus in the pool couldn’t it de-balance other chemicals in the water?
Also what could have caused this problem? Like I said up until this year and we have had the pool for 30 years we never had any problems like this.
Finally, is there a cheaper alternative to this instead of buying Calcium Plus?
Thanks for all the advice and help.
EDIT - I should add, is there anyway to fix the yellow stains? They are rather unslightly I might say.
