I've noticed since setting up my trident that my Alk typically drops after water changes -- this seems odd to me because I've recently switched from Tropic Marin to Fritz RPM which should be between 8-9 dkh and my tank has always been in the low 7's. So tonight I mixed up 5g of water to 35ppm (calibrated refractometer) and tested it. And it was LOW like 5.8-6dkh...
Is there something with mixing saltwater that can precipitate out the alkalinity? My Tropic Marin salt was always low too... I've never really been able to get my dkh up to 8-9 where I want it.
I'm starting to think maybe it's me, not the salts... I dosed my water change water up to the DKH I desired with BRS 2-part, but this seems less sustainable than just using a salt that mixes correctly.
