The tank is a redsea reefer 425xl with at least 50 corals in there. I have been using a doser everyday with Seachem products - 40ml of CA
, 40ml of KH
and 45ml of Mag. Using redsea and salifert test kits, my test results this morning was CA
= 420, KH
= 7, Mg
= 1350. How can I increase the KH
without affecting the CA
Any advice is appreciated. Thank you.
