by the way, is fun watching chemistry in this cool water
takes forever for FC to drop from 11 to 5
have had to back wash out an inch or two of rain water 5 times so far and then found
CH to be 220
and CYA so low as to be basically unreadable
TA seems to hang in there at 60 or 70
pH creeps up but then it always does in this pool (pt of acid now and then is SOP)
skin of ice two or three times but melts fast when pump goes on
found a dead mouse, I think the flesh had not decayed at all; looked felt like a living mouse save rather stiff
worst problem is black ice on the slate surround, treacherous
any way is fun
