- Monzter CM157 Internal Calcium Reactor - Skimz
Skimz has now updated their mini calcium reactor line with the Monzter CM157 internal calcium reactor. With most standard calcium reactors you will need a dedicated feed pump which can malfunction and clog causing inconsistent flow rates through the reactor. With the CM157 reactor, the circulation pump does double duty as a feed pump making adjustments that much easier. With a specially designed inlet to the reactor fresh tank water is pulled into the reactor at the rate the effluent is allowed to exit while recirculating the water within the reactor to contact as much reactor media as possible. With the QuietPro DC pump, the RPM of the pump can be controlled for fine tuning.
- Pump: Controllable Skimz QuietPro 2.0
- Power consumption: 22W
- Media: 3400 mL (14.25 cups)
- Method of feeding: Self-suction water intake
- For Aquariums up to 300 gallons
- Includes pH probe holder
- Includes Bubble Counter
The Skimz Monzter CM157 is a small calcium reactor packed full of features. With a built in pH probe holder; bubble counter, easy to use fittings, and an integrated feed and recirculation pump these are one of the most economical and compact reactors on the market today.
Calcium reactors replace the trace elements consumed by corals as they build their calcium carbonate structure. Typical calcium reactor media is made up of skeletonized coral fragments that will break down at lower pH levels. The calcium reactor will require CO2 to be injected into the reactor by the means of a regulator and solenoid (sold separately). The CO2 then go through the bubble counter to visually monitor how much CO2 is being allowed into the calcium reactor to lower the pH of the water within the reactor. The low pH will allow the media to be broken down into the trace elements that make up the skeletonized corals concentrating the recirculating water within the reactor. The effluent leaving the reactor will have a very high concentration of the dissolved trace elements from the media, as well as a low pH. The pH within the calcium reactor should be monitored as well as the effluent coming out of the reactor. Too low of a pH or too much effluent coming out of the calcium reactor can cause low pH within the reef tank.

Small footprint, could use some tweaking By Dan on 7/31/2019Dan would recommend this product to a friendThe O-ring on the lid is difficult to get in place. The solution I found was to heat it up in hot water so that it stretches better and sit in place while the lid is put on.
The pump does seem to struggle to prime. If it's at less than full power it won't prime on it's own.
Past those issues, I've been running it now for ~5months on an SPS dominant tank. It puts out a pretty stable effluent which was something I was concerned might be a problem. Love the space saving design that doesn't require a huge footprint in my sump.
Terrible design By Rob on 3/31/2019Rob wouldn't recommend this product to a friendO-ring will not go back in place. There’s no “seat” for it. The thing never “primed” after 30 min of running. I would advise to not skimp on money and go this route, like I did.
Silent Pro Pumps are garbage By charles on 3/9/2019charles wouldn't recommend this product to a friendA friend and I both ordered the same cm157 unit, both arrived to our home (hopefully) brand new. Neither one of our units had a working pump. It twitches for a second then turns off!!!!!
How deep does the calcium reactor need to be submerge to operate? I would like to place the reactor on top of Marine pure bricks that I have in my sump.
Thanks for getting in touch with us in regards to using this reactor. For this you will only need to have the pump submerged in order to get it running. You would need about 6" of it submersed in order to achieve this. Please let me know if there is anything else that we can assist with. Thanks!
