by AquaNerd | Jul 15, 2014 | Equipment, Science There’s a new nano sized protein skimmer hitting the market really soon from JBJ USA called the SK-45. Ideal for tanks up to 45-gallons, this new skimmer was purposefully designed to fit in the rimless JBJ aquariums, specifically the RL-45, RL-30 and the RL-20. It has a total footprint of just 3.75″ x 3″, which also makes it a good candidate for other nano aquariums as well. As far as features go, the SK-45 uses a needle wheel pump with an adjustable venturi valve, a height adjustable outage pipe that controls the internal water level, a large column for microbubble removal, double media sponges, large collection cup, and a mounting bracket for rimless aquariums. On top of those features, JBJ is also offering a limited one year warranty and, more interestingly, a free media sponge replacements for every six months over a two year span. The SK-45 will officially launch in a couple of weeks, but if you can’t wait until then to get a glimpse at it in action, feel free to check out the video below.
