Hi All. What a great site!
I'm near the end of a new pool install and, being a bit impatient, do not want to wait another week for the installers to come out and adjust my water so am hoping I can get some advice here.
12,000 gallon viking carmel (fiberglass)
3/4 hp hayward pump
aqua comfort 125,000 btu heat pump (anyone have one of these?)
hayward SWG with t-9 turbocell
Ok. The electrician hasn't arrived yet, so the heat pump and SWG are not yet functional. I have the filter pump running on 110 for now.
Salt has not been added yet. This will be given to me by the installer when they come out for the final visit, but that is at least a week away and I would like to get the pool up to SWG chemical levels now.
So my first question is if I bring the levels (TA, CYA, ph) up to the recommended SWG levels *before* salt is added, will the addition of salt, in a week or so, skew the levels?
I already added 1/2 of the needed CYA, bringing my CYA level to 40ppm and added chlorine bleach to 24ppm as an initial shock. I wasn't trying to get the FC that high. I'm using 'Pool Snap' iPhone app and was trying to bring FC to 14ppm, but after an hour or so, measured it at 24ppm. I was surprised it was so high, but didn't to an initial measurement as I assumed there was near zero chlorine. The CC level was measured at .5 or so, but maybe only waiting an hour isn't enough time to get an accurate CC reading?
Question: When should I add the rest of the CYA to bring it to the target (SWG) level of 80?
Final question... I have a 12 1b bag of arm & hammer and, based on my current TA of 50ppm, want to add 3.5 lbs. of baking soda to bring the TA to 70 (pool snap). I do not have an accurate scale handy, does anyone know how much a cup of baking soda weighs?
Thanks for being here to help at the start of this new adventure!
