Noticed a few frags in the sand bend RTN'n.
Checked parameters Ca 425 PO4 0.09 ALK 7.6 It has been falling for a week now & I have increased doser from 30ml per hr to 40 & it still fell from 7.9 to 7.6. I have been increasing the ca from 390-425 in the past weeks. Double checked with new Hanna reagent & it read the same 7.6. Checked with Red sea & it was 10.9???????? Maybe Hanna checker went bad?? The color of the solution looks low. I check every 2-3 days & you can tell by the solution if it is real high or real low just by looking at the color & it is definitely a light color with both solutions?????? Why would the ALK drop so much, even when I have increased the dosage by around 240ml/day?????? Something is going on, doing a water change tomorrow & will try to get someone elses Hanna checker to compare. In my short 2.5 yrs with SPS, ALk seems to be the culprit of RTN most of the time. Any ideas??

I tend to trust my Salifert and Hanna more that Red Sea for alkalinity. However, I've noticed that the Hanna does get weird near the end of the bottle of reagent.
