Just put together my Algae Reactor! Here's the full build: All the parts used for this algae reactor: AquaMaxx Reactor XL: https://www.marinedepot.com/AquaMaxx_Fluidized_GFO_and_Carbon_Filter_Media_Reactor_XL_Chemical_Reactors-AquaMaxx-UJ5313-FIFRISCR-vi.html LED Grow Lights: https://www.amazon.com/gp/product/B01MRHQMYH/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 Clip on Fan: https://www.amazon.com/gp/product/B012BKZC86/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 Aluminum tube: http://www.speedymetals.com/pc-4689-8379-6-sq-wall-sq-tube-6063-t52-aluminum.aspx Heatsinks: http://www.heatsinkusa.com/4-850-wide-extruded-aluminum-heatsink/ The idea is to use a huge reactor to allow the chaeto to grow quite a bit before needing pruning. It also just increases the water volume for my system, and I have the space. The LED grow lights I got because another forum member used them, and said they didn't get to hot. But after trying it for a few hours, the lights got REALLY hot to the touch, so I was worried it would damage the reactor. People mentioned this, and I think it was time to really try to cool it down. Aluminum should be really good at conducting heat. So I went for an aluminum tube. But without fins or a heatsink, the aluminum is bad at passively passing the heat off to the air, so it basically just traps most of the heat in itself and inside the tube. I got two 8" long heatsinks (that are about 5" wide) and used a bunch of thermal paste (arctic silver) in between the tube wall and the heatsink, and attached them firmly with JB Weld. That worked well for passive cooling. I went the extra mile and attached a clip-on fan above the whole unit to move air out of the tube and to pass fresh air through the fins. After a day of running it, everything is nice and cool. Hopefully the chaeto grows! Chaeto from reefcleaners.org. A great source that grows chaeto in a fishless system. Hopefully also without any other nuisances or pests.
