Hi Ben - just a quick update.

Noon today - added 4 oz polyquat
2pm added second trichlor puck to skimmer to maintain/inc FC after polyquat addition
3pm added app 18 oz borax to skimmer due to pH of 6.8-7

8PM testing
OTO TC =2 pH = 7.2
DPD FC = 2 pH = 7.2

FAS-DPD FC = 2 CC=4 pH 7.2 alk 70

I am adding nothing at this time.

I will retest in am and add more borax if needed. Let me know what I should be shooting for in terms of FC levels so I can add pucks as needed. And when/if I should re dose polyquat. Thanks! aciam
