Moderator note - Moved from here: Trichlor tablets can work - Page 2
I hope this is an appropriate thread in which to add this question. I have exclusively used the TFP method this year for my pool maintenance. After the initial SLAM it has been crystal clear and I have had to add nothing but 8.25% Clorox and muriatiac acid. Previously I was using calcium hypochlorite and sodium bisulfate but I did not understand the relationship between CYA and chlorine level so I was still getting some algae growth.
Anyway, we are going to be gone for a few days and would like to use trichlor pucks to keep the chlorine level up during that time. I am not sure exactly how to do this. Is there a relationship between how many pucks you place into the skimmer basket and what chlorine level is produced? The CYA level is currently 30, so I expect that a week or so of trichlor pucks will not raise it too much. I would like suggestions for how to go about this. I do leave my pump and filter running 24/7. Thanks in advance!
