So I've been searching all over and can't get a definitive answer on when to test. I just started using the BRS 1.1ml dosing pumps with BRS 2 part. What is the best time to test alk and ca? I tested tonight just before the pumps started and my alk is at 7.2 way too low as I'd like to keep it around 9 my ca is at 415. I've been dosing 15ml the last three nights and the pumps run from 11pm to 10am. Should I test during the day or just before the pumps start pumping? One other question is should I dose to bring it up first or just bump up the amount my pumps are dosing? Thanks guys I'm real green to all this dosing stuff.
