So I'm 10 months into reefing and have been using the Redsea Foundation kit and had Alk/Calc sitting nicely.
So when the reagent ran out I bought Hanna kits for Alk/Calc.
I have never got near the readings I was getting with the Redsea. Every test has been at least 40ppm higher.
So I turned off the dosing pump for calc for a few days to drop to where Hanna says 420 as I wanted. Nope even with pump off Calc was rising.
Yesterday I measured Calc at 464 up from the day before. So I did a 2nd test. Surely it can't go up with corals using it? So next test was 560. what the heck
I had enough so went to the lfs and bought a NYOS kit and tested. Pretty much the same titration method as Redsea at 1/2 the cost.
Calc measured 400ppm. As expected it's being depleted.
Possible bad reagent lot? on 2nd refill
Possible I'm doing it wrong? Followed exactly the BRS/Hanna instruction.
Help me Obi Wan. You're my only hope
