VarioS CR140 5.5″ DC Calcium Reactor (OPEN BOX)

Perfect for tanks up to 250 GallonsDimensions – 12.2″ L x 9.1″ W x 23″ HControllable DC Powered VarioS 2 PumpReverse Flow and CO2 Recirculation DesignAuto Fill Bubble CounterProbe HolderEasy to Remove LidEffluent Control Valve1/4″ Push Connect FittingsInternal or External ApplicationNeptune Apex ReadyPerfectly 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.Recommended Tank Size:High Ca/Alk Demand – up to 125 GallonsMedium Ca/Alk Demand – up to 200 GallonsLow Ca/Alk Demand – up to 250 GallonsSpecifications:Body Size – 5.5″Footprint – 12.2 x 9.1″Height – 23″Media Capacity – 1 gal (3.8L)Inlet Tubing Size – 0.25″Max Feed Rate – 150 GPHMax Wattage – 25W @ 120VACWhat’s Included?1x CR140 Calcium Reactor1x VarioS 2 DC Pump1x Pump Power Supply1x Pump Controller2x Push Connect Ball Valves2x Suction Cups1x Inline Check ValveTubingWhat Else Is Required For Use? (not included)CO2 Regulator & Solenoid – We have had great success with the CarbonDoser from Aquarium Plant LifepH 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 thehead loss. In most cases, a needle valve or gate valve can be used to decrease the flow if your pump is too powerful.Reactor Media – Most media will be made up of crushed coral skeletons. In most cases, we suggest using a course media like Two Little Fishies Reborn or Elos CaPur.
