My Reef Creations has been brandishing a slew of production activity lately and they’re back at it again, this time with some design polishes to their CR-2 calcium reactor. The new design features rounded corners, beveled edges, a convex front side of the bottom plate and a fancy new decal. We’re not seeing any significant operational design changes but when it comes to plumbing the circulation of water through a media chamber, there’s only so many ways to target feed a coral. Now Raj and Tim should be expecting us to give them the stinkeye for their perforated spray bar down the center of the media reaction chamber. We’ve already hassled them that the majority of newly set up small and large calcium reactors opt for fast flowrates with very coarse aragonite; this media is more or less weathered coral bones, and one big advantage the coarse media has over the old type of crushed coral is a greatly reduced buildup of sludge. Other than adding new media, removing and cleaning this sludge from the reaction chamber is the only other maintenance that calcium reactors require. MRC contends that the use of crushed coral aragonite with this spraybar reduces sludge buildup and improves flow through the reactor media. Whether one type of technique is superior to another, we do not know but owners of the MRC CR-2 will totally be able to pull out the spray bar in case they want to use the fast flow and coarse media technique. We’re just saying. In any case, golf claps for MRC for paying some attention to making reef gear a little easier on the eyes. More pictures after the break.
