Recent convert to BBB and looking good so far. Reading as follows:
I check pH and FC in the evening, add bleach as required. I shut the filter down before I go to bed and turn it back on in the am. Saturday morning complete chemistry with the TF100. Like many, still a little unsure of the CYA reading, but it's close (need to buy the 50 ppm standard).
Currently have some 3" pucks in a floater (just returned from vacation). Will likely discontinue these after they are fully dissolved (until next vacation).
My question: Since FC decreases during the day, should I be taking my FC reading in the morning and adjusting then or am I OK the way I am doing it now. I remember reading some advice on a forum some time ago, but cannot find it. (By the way - I checked the FC reading this morning and it is just where I expected it to be based upon last night's addition, so little or no overnight loss).
