Perfectly dial in your recirculation flow rate with the DC powered VarioS 2 CR140 Calcium Reactor. Calcium reactors are capable of maintaining a balanced ratio of calcium, alkalinity, magnesium, and other trace elements by dissolving aragonite medias with carbon dioxide gas which drives down the pH of the water to an acidic level dissolving the media releasing elements that your corals will use to grow. Reef Octopus Calcium Reactors are made with high-quality materials and can be one of the most cost effective calcium alkalinity solutions for larger reef tanks.

What Else Is Required For Use? (not included)
CO2 Regulator & Solenoid - We have had great success with the CarbonDoser from Aquarium Plant Life
pH Controller & Probe - The Milwaukee MC122 is very reliable and is our go to standalone pH controller. A slightly better option would be an aquarium controller like an Apex with a dedicated probe for the reactor.
CO2 Tank - We carry a 5lb CO2 Tank that will last the average tank around 6 months to a year. You can usually find a local welding gas supply shop to fill your tank, but a better source would be medical or beverage grade CO2. Do not use CO2 that is used in paintball guns.
Effluent Feed Pump - We suggest a pump that flows around 150 GPH after the head loss. In most cases, a needle valve or gate valve can be used to decrease the flow if your pump is too powerful.
Leaking By Johnny on 3/15/2020Johnny would recommend this product to a friendThe point where the clear colum conects to the top black plate came apart and leaked alot of water destroying a $400 pump. Luckly no fires. Anyhow, I gave it a 4 four star because it is a great design and manufacturing defects do happen but they should do a better job testing before selling as these items can cause a lot of damage if they fail.
Amazing Cx Reactor By The Sealed Reef on 12/16/2019The Sealed Reef would recommend this product to a friendI've had this running for about 3 months now. Incredible growth, consistent alk at 8.3, calc at 420. My corals have truly taken off and could not be happier with this particular application. I use the BRS Co2 tank and the regulator from CarbonDoser. Highly recommend.
Great quality and simple to setup By David on 6/22/2019David would recommend this product to a friendI’ve been using this calcium reactor for a few months now and I’m glad I went with reef octopus over the competition. For starters the build quality is amazing and it’s simple and to the point. The varios pump has been working flawlessly and is dead silent. Highly recommend this reactor over the competition.
