This combined with its rectangular shape (have you ever seen a round refugium?) mean that the right light goes right where you need it – and minimizes nuisance algae growth in other areas of your sump due to light spillage. The GRO uses all its power to emit light in two specific wavelengths that are optimized for macroalgae growth – 455-460nm and 620-670nm. A “start” of macroalgae such as chaetomorpha – get it online, from a LFS, or from a reefkeeping buddy. A sequestered place in your sump or filtration area that has adequate water flow.Ģ. Growing macroalgae opposite your normal light cycle (called reverse daylight photosynthesis or RDP) also helps raise and stabilize your aquarium pH.Only three things are necessary to get started:ġ. It also creates a home and reproductive area for beneficial micro-fauna that consume waste and provide a food source for corals and fish. REDUCE YOUR NUTRIENTS, THE NATURAL WAY, WITH A REFUGIUM It’s easy! Growing and harvesting macroalgae in a compartment in your sump, or in a full-blown refugium, is the natural way to reduce unwanted nutrients in your reef aquarium. Power the GRO using an available DC24 connection in your Apex ecosystem (on Energy Bar 832 or 1LINK module). If you do not have an available DC24 port, or you wish to use the GRO without an Apex, a power supply is available ( Sold separately ) so it will operate standalone.Īn available gooseneck mount comes in two models: This has a unique pipe-clamp mount to attach it to your existing plumbing above or behind your sump. This means it can safely be placed close to the water surface, maximizing light effectiveness, and reducing wasteful light spillage that often causes nuisance algae in other parts of a system. The GRO is IP64 rated which means splashes and salt spray will not take it down. Also, with its low-power, distributed LED design, the GRO can be placed very close to the water surface further limiting light spillage and therefore nuisance algae. Since most refugia are rectangular, the GRO projects light in a similar manner.

Nuisance algae on in our sumps and on our equipment is normally one of the downsides of using a refugium. With the GRO, the 84 LED in a rectangular form factor create even light intensity and no hotspots. This causes hotspots that lead to algae burning or stunted growth. Round, spotlight style refugium lights, often create uneven spread of intensity. The GRO can effectively cover a refugium area up to 18?x24? Large, rectangular form promotes better algae growth, while reducing nuisance algae from light spillage, as intensity is evenly spread across a refugium area that is almost always rectangular. Two key wavelengths for algae photosynthesis are emphasized - 455-460nm and 620-670nm. It plugs directly into any available DC24 port in your Apex ecosystem, or alternatively, it can also be run completely standalone (PSU WILL BE AVALIABLE SEPERATELY SOON)Ĭompact, flat, rectangular LED grow light measures 8.7? X 6.1? X 1.4? making it the perfect fit for the smaller refugium compartments in many modern aquariums - as well as those that wish to grow macroalgae in a separate refugium.Ĩ4 LEDs in four colors create an evenly distributed spectrum optimized for macroalgae growth. Chaetomorpha) using a specialized light spectrum which maximizes photosynthesis. The GRO is a specialized, 20W LED light designed to grow many types of common macroalgaes (i.e. Some of the most successful reef aquariums employ the use of a macroalgae-filled growth area or refugium for the purpose of nutrient control. PLEASE NOTE THAT CURRENTLY THIS WILL REQUIRE A APEX SYSTEM TO RUN OR A STANDALONE PSU Maintaining low nutrient levels is key to a healthy and algae-free marine aquarium
