I have a 150g tank with a 40g and 60g sump.Mixed reef, have about 11 SPS frags and 20 LPS varieties. Nothing huge but med size hammer, torch and BTA.
I have been using salifert alk test and just recently bought a new hanna alk tester. Now here is the problems. Usually a few days after a water change I would get 7.8ish on salifert. It was going down to 7.3 after a week. Figured I would need to start dosing a little so I picked up dosers.Not in use yet.
First test with hanna was 7.3. Right on. Every test after has been 8.5 ish. Tip on, tip off.Vials rinsed
in rodi after.
So I am really confused. Before WC today I just tested my tank and fresh fritz salt at 35p.
Salifert: tank 6.9 Fresh Fritz 8.7
Hanna: tank 8.5 Fresh Fritz 10.4
I will also mention I have 2 salifert alk tests since this craziness. No difference there.
Took sample to LFS and they used salifert and came in at approx where I am with my salifert. What gives here? Any thoughts on what you would do? I am leaning salifert at this point.
