The Skimz Monzter CM113 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.
Great Reactor! By Chad on 1/19/2017Chad would recommend this product to a friendI did a lot of research on reactors and have been a 2 part guy for years after watching Ryan break down 2 part dosing so well on BRS TV. One thing that always prevented my purchase of a reactor was the amount of room you have to have available for all of the equipment. Obviously you will need a CO2 tank/regulator, that will be out of the sump, but being able to stick this guy into the sump area is real bonus. For the reactor's capability the footprint is only about 6 in by 6 in. The build quality is great and the fact that BRS stands behind these is another bonus.
The research that I did though came up pretty short on some of the questions I had that aren't really explained that well in the review or in the manual. First of all, the pump is encased nicely and should hold up well to the lower pH inside the reactor. The mystery of how it could serve as recirc and effluent pump is solved once you can see that there is a small tube that goes from the inlet of the pump to the bottom(allowing water in) of the reactor acting as a venture that is stronger with increased pump speed. For my setup I have found that only the lowest RPM's on the pump is necessary for good effluent output. Also the pump pictured is shows an opening on the front that I thought was the inlet, actually pulling water down and pumping it up. The flow actually is upward as the pump pulls water from the top near the lid and outputs in down near the pump creating almost a swirling venturi-like motion when a few bubbles get into the pump.
I would agree with the other reviewer that the gasket is impossible to keep down, but once you learn the trick it isn't too bad. If you place the gasket onto the body and hold it with you finger in one spot it will stay. So I figured out that if you place the gasket on and hold it with a small screwdrive, spatula, toothpick etc, something small enough to fit between the lid and body you can hold the gasket while closing the lid and it will stay in place just fine.
All in all I couldn't be happier with this product for the features and the price.
Good quality By Blue on 2/26/2016Blue would recommend this product to a friendJust taking a break from trying to reinstall the top cover after filling with media. It is incredibly frustrating to install while making sure the o-ring is seated correctly. The design requires a third hand. However, overall quality is quite good for the price. I would rate higher if o-ring placement was better designed. Back to getting this thing online. Glad it's done infrequently.
