The concept of using macroalgae as a method of nutrient export is not new. However,the introduction of the ARID (AlgaeRemediationIlluminated Device)theoriginal,patentedmacroalgae reactorby Pax Bellum is a quantum leap forward. This ingeniousdevice utilizes macroalgae (specifically Chaetomorpha) to function as atunablenutrient exportmechanism. The unique design of the ARID incorporates a coaxial LEDlight tube to maximize light penetration and efficiency.The tube and flange designofthe device serves to isolate the algae from atmosphericCO2, which effectivelylimits the carbonsource for the algae toonlythat which isrespired by organisms within the aquarium.This is a self regulating feature andeliminates organic carbon buildup(yellowing of the water).The ARID isanalogoustoalung for the aquarium, bysupersaturatingthe aquarium with oxygen createdby thealgaeduring its respirationwhileremovingexcess CO2. Pax Bellum recommendsrunning the ARID on a "reverse daylight" cycle (i.e.; opposite of the display aquarium)which helps tobalance the natural day/night pH swingthat occur, and tomaintainhigh dissolved oxygenlevels throughout the night when the display aquarium lightingis off and photosynthesis has ceased.
TheARIDis capable ofTargeting SpecificNutrient(s) forExport. In the reefaquarium the mainconcern is balancing the nutrients N:P:K:C, with the goal oflimitingphosphate(P).Usually never in short supply,Potassium (K) and carbon (C) arenotdosed. However,Nitrogen (N) can become depletedrapidly by the growth of algae,causing growth to stall. To keep the algae growing, the aquarist should dose the,“Nitrogen+Molybdenum”solutionthat came withtheARIDreactor,at a rate tomaintaintheratio of NO3 to PO4ata minimum of 20:1 and ideally at100:1(example;3ppmNO3to0.03ppm PO4). Maintaining this ratio will allow the Chaetomorpha or macro-algae of choice to continue to grow until phosphate levels reach the minimum cut off forgrowth at 0.02ppm
Usethe ARIDwith theTriton Method:One of the reasons we love thisproduct is dueto the fact that it is satisfies the need for the algae component when running the TritonMethod. 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 algaecomponentroughly 15-20% of the system volume.For aquarists that currently lack the space orability to incorporate a large algae filter in their existing or new setup, this upright,sealed unit offers an excellent alternative. Because of the fast growingnature ofChaetomorpha algaeespecially in this reactor, we recommend placing it in the upperhalf,if placing other algae in the same unit.Use the ARID with aCalcium Reactor.
