Sand doesn't wear out so yours is fine. Many people have their sand for many more years than 6-8. Sometimes you have to top it off some though. 8 lbs. of CYA should be just right.

Re: Finished renovation first test numbers are in!
I've been adding about 1/2 gallon 8.25% a day. I suppose that means I'm losing about 2ppm a day.
FC 4.5
PH 7.8-8
YA 150 ish from previous measurement
CYA 45 ish from previous measurement
I wonder if I'm going to have problems with my PH bouncing around. I'll just monitor for now I guess.
