125 G Reef Tank heavily stocked with LPS & mushrooms, Zoas, 3 tangs, 1 mandarin, rock blenny, clownfish, 5 reef chromis, zebra moray. 100G sump, AquaC Ev180 skimmer. I am tired of dosing Kalkwater and was thinking of buying the Korallin 1502 or 3002 Calcium Reactor. Does anyone have any recomendations? Korallin states that a PH controller is not needed with this system. I think that I would integrate one anyway. If Korallin is not desirable, please recommend a suitable substitute..... THANKS!
