Assuming borate level of 0 (I have test strips on the way) and 44,000 gallons, I'm working on my calculations for adding borates.
Last full test follows.
So is 80 too high a TA? Poolcalculator.com shows a range of 70-90. I'd like to know more about this! I see I'll need to create some sort of fountain, this is going to be difficult on my pool since they didn't install fittings on the returns back 50 years ago. I truly have no way to attach anything to send water above the surface without making some sort of friction type attachment such as a smaller size of PVC than the copper return, wrapped with some sort of rubber that will fit the fountain by a pressure seal.Originally Posted by chem geek
I'm considering adding the boric acid due to the volume we are talking. It should end up being a whole lot easier than messing with a bunch of muratic acid (albeit only 5 or 6 gallons) and 30-35 boxes of 20 Mule Team. Not sure where to get it, I don't see it at Leslie's, and have a request in at Poolplaza.com (they are very close to my home). Even with boric acid, we are looking at 14 gallons of liquid or 100 lbs of powder (if it exists). Of course that's to bring it up to 50, and I'll be shooting for 30 at first so I'll have some extra for a while.
