PaxBellum ARID N18 - Macroalgae Reactor up to 450 liters


This ingenious device utilizes macroalgae (specifically Chaetomorpha) to function as a nutrient export mechanism.

The unique design of the ARID incorporates a coaxial LED light array housed in a tube to maximize light penetration and efficiency. Vapor heat pipe technology keeps the LEDs running cool for maximum light emission and lifespan while keeping the heat out of your aquarium. The LEDs were selected to supply intense PAR (photosynthetic active radiation) for rapid macroalgae growth. Maximum nutrient uptake is ensured by pushing system water evenly through the macroalgae mass.

Eliminate the clutter around your aquarium the ARID can function as a stand-alone filtration system. Designed to replace GFO (granulated ferric oxide), nitrate reactors, bio-pellet reactors, carbon dosing and even protein "skimmers" (foam fractionators). The ARID can perform functions the previously mentioned equipment can`t. Functions such as, increasing and stabilizing Ph from day to night, lowering dissolved CO2 concentrations, keeping dissolved oxygen even from day to night, and increasing dissolved oxygen to levels higher than can be attained with skimmers alone, all standard benefits of running the ARID system.

Small but mighty… The N-series (aka Nano series), N18 and N24 with its acrylic construction, are marketed for the aquarist that collects and displays their kit just as passionately as they collect and display the organisms residing within the main display. The aquarist can easily remove the light cover to reveal the inner workings of the opaque acrylic chamber and inspect the growth of the macro-algae inside. Highly polished acrylic edges are found throughout the N-series. The N24 has additional chamfered edges on the lid, flange, and base. The profile of the N24 mirrors that of the C-series while the N18 striving for the smallest envelope forgoes the recognizable ARID gear shaped profile for a more simple and compact form.

For the aquarist with a system from 150-450 liters (40-120 US gallons) the N18 is the smallest practical use of the ARID reactor embodied in a H.O.T. version.

This model stands 42 cm (16- 3/8”) tall, and has a footprint of 16,5cm (6- ½”) in diameter; the chamber and lid are produced entirely out of cast acrylic. The H.O.T. bracket is integral to the chamber flange and is adjustable for tank rims with bracing. The central inlet port on the bottom is ½” barb, as is the outlet on the lid. LED power consumption is 12 watts. Optional in-line quick-disconnects are available for the N18 separately.

To contain the blinding light emanating from within the reactor included is a magnetically fastened removable light blocking chamber cover.
