I've set up a tank, which at the moment only has a couple of clowns and cheato luckily.
It's a barebottom with Aquaforest rock. Since it's a new tank with no corals, I've not checked Alk often, only NO3 and PO4.
I use RO/DI, which I check regularly, and my instant ocean mixes to 11 dKH, but, I have no idea why, this tank has 14 to 15 dKH.
I've checked the salinity with a refractometer and the Dupla precision hydrometer. It's 35 ppt.
I've double checked my hanna checker against a standard solution. The hanna checker only measures 5% higher than the standard solution (which is admittedly a bit old, even if well preserved).
Where am I getting this crazy Alk from and is there a calculator somewhere to lower it?
