Re: Time to replace sand?
Yes. Here are today's results through of 3pm (weather here in Maryland is sunny, mid-80s, low humidity, light breeze)
8:30a FC 17.5, CC 1.5 - added .3 gal bleach (using Taylor K-2006) - increased FC by 1.5
11:30a TC between 18 and 25 - added .7 gal bleach (using old kit because I ran out of titrating reagent) - increased FC by 3.5
1:30p TC 25ish - nothing added
3:00p TC between 18 and 25 - added .7 gal bleach to be on the safe side - increased FC by 3.5
I will test TC again in an hour or so. My bleach is 12.5% so each gal should be upping the ppm by 4.8.
