The concept of using macroalgae as a method of nutrient export is not new. However, the introduction of the ARID (Algae Remediation Illuminated Device) the original, patented macroalgae reactor by Pax Bellum is a quantum leap forward. This ingenious device utilizes macroalgae (specifically Chaetomorpha) to function as a tunable nutrient export mechanism. The unique design of the ARID incorporates a coaxial LED light tube to maximize light penetration and efficiency.

The tube and flange design of the device serves to isolate the algae from atmospheric CO2, which effectively limits the carbon source for the algae to only that which is respired by organisms within the aquarium. This is a self-regulating feature and eliminates organic carbon buildup (yellowing of the water). The ARID is analogous to a lung for the aquarium, by supersaturating the aquarium with oxygen created by the algae during its respiration while removing excess CO2. Pax Bellum recommends running the ARID on a "reverse daylight" cycle (i.e.; opposite of the display aquarium) which helps to balance the natural day/night pH swing that occur, and to maintain high dissolved oxygen levels throughout the night when the display aquarium lighting is off and photosynthesis has ceased.

 

Use the ARID with the Triton Method: One of the reasons we love this product is due to the fact that it satisfies the need for the algae component when running the Triton Method. This method relies heavily on algae as the heart of the filtration system. Nutrients, namely No3 and Po4 are largely kept in check by an algae component roughly 15-20% of the system volume. For aquarists that currently lack the space or ability to incorporate a large algae filter in their existing or new setup, this upright, sealed unit offers an excellent alternative. Because of the fast growing nature of Chaetomorpha algae especially in this reactor, we recommend placing it in the upper half, if placing other algae in the same unit.

Use the ARID with a Calcium Reactor. Purchase the Ca injection assembly (Ca Reactor Feed and Injection Assembly) this compact manifold threads directly into the water inlet on the base of the ARID n24, c30, c36 and inline with tubing on the n18. The assembly can be installed or removed at any time by the aquarist. This optional kit sends water directly to a Ca reactor or peristaltic pump supplying the Ca reactor, and receives effluent from the Ca reactor. This is accomplished by separating the high and low pressure ports by a user preset valve. The effluent coming from the calcium reactor passes through the included drip counter, and then enters the low pressure side of the calcium injection assembly where it mixes with the bulk of the water entering the ARID, making contact with the macro-algae where it is stripped of excess CO2 and PO4 before entering the reef system. This optional kit can increase the growth rate of your macroalgae and with it the nutrient uptake rate and dissolved oxygen production.
