calcium reactor

Selling a Reef Octopus CR200 calcium reactor. Bought it as part of a set but the reactor is too big for where I was planning on putting it, so selling or trading for a smaller one. Located in the California Bay Area but can also ship at your cost...

I’ve been dosing All for Reef for a month now, it seems like a good product. At first it brought my high levels of Alk down to proper levels. Calcium levels has been stable around 440/450. Calcium has started to drop more frequently and Alk has risen back to 14/15KH. I remember watching a BRS...

I had bought this years ago used and only ever used it as a second chamber to my main Calcium Reactor that I sold off year ago. It’s missing the pre-filter and RO tubing, don’t think you have to have the pre-filter and RO tubing is cheap. . Has the CO2 bubble counter and there are no cracks. I...

looking for a large AquaMaxx or Reef Octopus calcium reactor in good shape. Thanks!

I have a 44 pound box of large reborn and I have all the other stuff that I have normally mixed in it for years, and I’ve had wonderful success. It’s a blend of others and size. It’s all in the pictures and it’s probably $300 -350 worth of media.

Hi all I was just wondering if anyone here has any experience with the AquaMaxx calcium reactors, specifically the T3 model? I have a 300 gallon reef tank that I'm currently dosing with kalk, but I know I will eventually move to calcium reactor and saw this one on BRS. Other than a few...

Pardon my curious nature but : We try to change the PH of salt water by co2 and try to melt calcium reactor media (mostly between 6.1 - 6.6) - RODI water coming out of my system usually ph's around 5.8 - Question - Will it be crazy to put this media in ATO system to feed for alkalinity and...

Selling my GEO 624 calcium reactor $300 +shipping. Or pickup near Modesto ca.

I'm wondering if the circulation pump that circulates the water within the calcium reactor matters or not?

Been hoarding this for years. Those of you who know what it is know how rare these are to come across. Considered the Ferrari of calcium reactors that run rock solid for years. Hate to get rid of it, but would rather see a die hard sps keeper put it to work. Paid $600 for it. $500 will take it...

Hello all, new to the site but not reefkeeping. In the process of setting up a calcium reactor (reef octopus CR-140) trying to program my solenoid valve and there are a few conflicting programs I’ve seen on how to do this. I thought I would have a second PH prob being (pH_Tan) as a back up...

This thread is to study the effects of operating a super saturated small media bed CaRx (S3MBR) using the super saturation of CO2. The premise is that a S3MBR should be able to to achieve performance equal to, or exceed the performance of traditional larger CaRx reactors that rely on media...
