***Reduced Price*** I have a Reef Octopus Kalkwasser Reactor KS-250 for sale in Tampa, FL...going for $275 plus half the shipping cost. Better pics to be posted later today.
Changed to a Kalk Rx after 10+ years of running a CaRx on a 250g Mixed Reef system (fish, SPS, LPS, Soft, etc), tank pH had run 7.8 to 7.95 with Alk running 9.5 to 10.2 kh.
Currently, with a Kalk Rx, the pH is 8.05 to 8.15 with Alk at a steady 8.3 kh dosing 2.03 g/day across 48 - 3.5 min...
