TROPIC MARIN - kH Test Kit
The carbonates concentration should be kept between 7.00 and 8.50 mg/ l.
With kH values of this magnitude is possible to avoid a sharp drop in pH which may kill your fishes.
It is important to keep the concentration of Mg around 1350mg/l to force calcium and carbonates remain balanced.
Calcium
forms with carbonates and bicarbonates an insoluble compound called calcium
carbonate. Yes this is indeed an important building stone for corals and
calcareous algae but then it should be formed by biological processes and be
deposited at the right place.
