First, thank you in advance for your help. I found this forum 3 days ago and have been voraciously reading ever since! I wish I'd found you 3 years ago!
A little backstory:
We moved into this house August 2006, pool was built in 1989. Looked to be in pretty good shape, "inspection" was favorable. Since then we've replaced pretty much everything but the hole in the ground. The last 2 years we had an obvious leak - then last summer we were losing 3+ inches per day. Obviously this meant a constant chemical imbalance!
We have just had the following done:
New liner. New skimmers. New light. Added piping for automatic cleaner. Replaced all decking (previously brick pavers and rotted wood) with cement pavers.
So we had the pool refilled - about 60% trucked in, 40% from our well. Now I'm trying to get where I need to be, having never started from scratch. I've got the other numbers (TA, CH) up from 40 ppm, but I need to shock (not holding chlorine overnight at all) and I'm not sure the best way to do it. I bought a "real" test kit and this morning the results are:
TC = .5
FC = 0
pH = 7.4
TA = 110
CH = 200
CYA = 0? - Not sure I know how to use the test vial! The black dot never "disappears"...
I've got a big tub of Power Powder Plus from Leslie's, purchased some time last year (not sure why we ended up with this, it's not meant for vinyl, right?) - but is there any way I can use that up so I don't waste that money already spent?
Goal is to convert to BBB, so I've got about 7 gallons of 6% bleach on hand at the moment and it's on sale for 1.49/gallon across the street at our grocery store through end of June.
The water is beautiful and has been other than right after the first chlorine addition, it turned yellow. Looked like metals so I added 2L of Metal Free and has been clear since.[attachment=0:gacgei3w]pool051610.jpg[/attachment:gacgei3w]
