    How do you feed your calcium reactor?

    Stability is king in our systems and it’s hard to beat a calcium reactor when it comes to keeping alkalinity, calcium steady and with some magnesium media, that too. But with any potentially great do-dad in our sump, it’s limited by what’s plugged into it. So how do you guys & gals steadily feed...

    Calcium reactor issue (pH fluctuation)

    I have an AquaMaxx cTech T-NANO hang-on calcium reactor. I just set it up on my 11-gallon aquarium because I recently got my first stony coral frags and want to start maintaining proper chemistry for these corals. I’m using a Versa peristaltic dosing pump from EcoTech Marine to dose the...

    Calcium reactor and Kalkwasser reactor/stirrer

    Need help figuring out what to do on my next build and what equipment to run. Currently I mix kalk in a 5 gal pail then transfer it to my ATO. It keeps my Ph, calcium and alkalinity stable. I’ve been considering a calcium reactor but my pH is already low 7.8 and I’ve heard they can lower pH. Can...

    Help modifying calcium reactor for Kamoer pump

    So in setting up the bigger tank (link below in signature) I’m revamping my old calcium reactor which is a MRC CR-1. originally this setup was feed by a maxi jet 1200 pump and used a needle valve for adjustments. For the new tank I got a new Kamoer FX STP2 continuous duty pump to use as the feed...

    New SPS frags!!!

    Reefer 250 around 18 months old. Finally getting the hang of keeping sps. So I got rid of a big monti and went crazy with the sticks. This thing will be packed if I can keep everything in line. I've got 9 more frags to find spots for. I can't wait for these to take off!

    Media Reactors vs Calcium Reactors

    So I'm completely new to reactors and got an IM reactor in a recent tank pick up. I guess my question is, what is the difference between media reactor vs a calcium reactor? Can you use one for the other or are they completely independent?

    Calc Reactor pH swings

    What are your thoughts about how much daily or weekly pH swing is acceptable in your calcium reactor? This is pretty much what I get in the graphic below, about .1 pH variation per day. Is this typical? Is your reactor more steady?

    Correlation between Alkalinity and pH?

    Hi everyone, I have a 300 gallon mixed reef system, and I am trying to make my tank a tad more stable/automated since I am traveling out of state for weeks at a time due to school. I am switching from a bubble magus dosing system (using biotech two part solution) to a korallin calcium reactor...

    Calculating the initial calcium reactor flow volume

    I am working on setting up a Deltec Twin Tech CaRx and I am looking to calculate the initial flow rate for the effluent. I currently dose 2 dKh per day to my tank which has a net volume of around 820 litres. The reactor works on the total CO2 saturation, thus from my understanding the dKh...
