Figured it would be a good topic since its the new thing and alot of ppl are doing it. Getting a reactor and wrapping lights to me isnt DIY. Was looking for people to find the materials at a store or online to make one. Most GFO/Carbon reactors have a small dia. like 4" where as in a chaeto reactor there some where in the 8" dia. But thank you Ill look into and hope that RC Mods feel the way I do and keep it open.
