I have actually have all three.
- Avast K1 kalkwasser stirrer with an Avast 25 ml/min peristaltic feed pump
- Geo’s Reef CR612 CaRx & SMC415 secondary chamber, Watson Marlow 505u peristaltic feed pump and my custom DIY stainless Victor dual stage CO2 regulator
- Neptune DOS & DDR as well as a pair of BRS 1.1 ml/min dosers
Just trying to decide on which one to go with for this tank. This tank is new from scratch, no transfers. Either way, I’ll be taking my time as I want more fish and a few months of demonstrated stability before adding coral.
