tanks are up and running, only thing is rock so far. It's been a month and nitrates and ammonia are 0.

80 gallon reads 8.1, 2.75, and 390 for PH, ALK, and Calcium.

125 gallon reads 8.2, 4.5, and 360 for PH, ALK and Calcium.

I know the calcium is low....425 - 450 is good. And I think I am doing something wrong with the ALK test as that don't seem right.

Tanks have sand and rock plus some hitch hikers (crabs, shrimp, and plants)

Thanks for any help...
