Re: Time to replace sand?
Three titrating tests starting at noon today. Before that I had to use the shotglass method and it was a guess at best.
The water is still cloudy, but I can see the bottom.
1pm
FC 31.5
CC 0.0
4pm
FC 28.5
CC not tested
7pm
FC 27.0
CC 1.5
I'll test again tomorrow morning and see if the FC has held within 1 ppm. If it is below 25ppm, I'll add bleach. If it is 25 or higher, I think the plan is to stop adding bleach let the FC drift down to 15 (it may take a day or two), then test pH and TA. Then (dare I ask it?) will it be swim time?
