RK2 is an organization that’s synonymous with business sized aquarium life help gear, particularly large honkin’ protein skimmers. You’re extra more likely to see a 12 foot RK2 skimmer working behind the scenes of your native public aquarium however in recent times, RK2 has been onerous at work shrinking their know-how for ‘smaller’ saltwater aquariums.
The XFLO line of small venturi powered protein skimmers have loved a small however vocal following within the reefing passion however an fascinating bigger mannequin known as the 5-AC has lately caught our consideration. Apart from their stringent adherence to strict foam fractionating rules, the large differentiating characteristic between RK2 skimmers and nearly all others within the hobbyist aquarium market is their use of true venturi valves to inject air, as an alternative of the ever present needle wheel.
RK2 positively turned loads of heads at MACNA 2019 by mating up this medium sized 5-AC skimmer with a beloved and recognizable Ecotech Marine Vectra L2 water pump, making this one of many first Ecotech Marine protein skimmers in the marketplace. The mix of excessive quantity and substantial strain functionality of the Vectra L2 is a good match for the Mazzei venturi used to inject air into the RK-2 5-AC however one factor that’s actually piqued our curiosity is the efficiency score RK2 has bestowed upon this beast of a skimmer.
Certain this skimmer appears pricy with an estimated retail price of $2200 but it surely’s rated for between 1,000 and a pair of,000 gallons and also you would possibly be capable of bundle the RK2 5-AC with a Vectra L2 for round $2500. Though this skimmer definitely isn’t about to suit underneath anybody’s tank, examine that to any of the ‘premium’ acrylic cone skimmers with fancy needle wheel pumps that may simply attain $2000 to $3000 for what looks like rather a lot much less materials and far smaller quantity for fractionation to really happen.
We had some very good, prolonged conversations with the reps from RK2 and it’s about time we revisited venturi injected protein skimmers, each to spotlight the place they excel, and to border the purposes the place needle wheel designs are nonetheless a greater worth or just extra sensible. Seeing the RK2 5-AC working on a well-recognized pump just like the Vectra L2 definitely helps makes us really feel extra comfy about contemplating these ‘medium’ sized protein skimmers from a business aquarium life help model.
