I finally got a full set of tests run on the new pool.
FC - 6
CC - 0
TA - 90
pH - usually 7.8 or above
CH - 550
CYA - 50 (after addition of 8 lbs)
I know CYA could be a little higher, but I'm moving slowly, as I've never dealt with anything near this size before and definitely don't want to have to drain it. That's why I'm keeping my FC at 12% of CYA too, just to be safe. I've always preferred to run a little high, and there is sometimes a little algae where the waterfall rocks meet the water, right at the water line.
I was concerned about the CH being high and thought that might be responsible for the little calcium spots I posted about in another thread. But after further reading, I learned water chemistry doesn't have anything to do with that, so unless I start to see scaling, I'm not going to worry about it any further. It seems having too little would be detrimental to my heater.
So my biggest problem now is keeping the pH down. I'm adding MA like a madman, but the lowest I've gotten it is 7.5, and that only for a short time. I just measured TA for the first time at 90, so I don't know what I started with. I'd like to get to 50.
I'm running the IC40 at 100% for 6 hours/day. That's my total pump time as well, one hour at 6 am just to clear away the junk that blew in overnight, and then 4 pm to 9 pm because we like it running in the evenings while we're using it. I mostly keep the fountain and waterfall off to help with the rising pH.
