I'm starting a SLAM today. Water continues to be cloudy and chlorine usage has started creeping up. The last couple of days, to prepare:
Ordered an extra XL from tftestkits.net (and a speedstir for fun)
Good vacuuming of the pool floor
Good long backwash of the sand filter. Start up psi is 8psi.
Wife brought home a bunch of 10% with 16176 date stamps.
Hooked up the 'Lady Bug vacuum' and let it run. Set pump on full time.
Topped of the pool water level
Tested at 0830 this morning:
FC 3.5 (dropped from 8ppm at 0830 yesterday with no swimming but a lot of sun)
TA 60 (YEAH! Finally got it down)
CYA 39 (That's what I'm calling it. It was just below the 40 mark)
CH - don't care
Borates- about 11 ppm calculated, not tested
At 1030 I added
26 fl oz MA to get between 7.1-7.2 pH
272 fl oz 10% for a target 15 ppm FC
I'm initially going to test every 30 mins and maintain. I'll keep you updated! And I'll get an almost 'before' pic at the next test too.
