I was not prepared for all the changes in this hobby after leaving it for 12 years. I need some advice concerning my 20 nano that I'm currently cycling. I want the "norm" for phosphate and nitrate removal, but don't want to over do it. I have studied up on this GFO stuff (why is everything a dang acronym) and I know about carbon etc.. I'm just trying to figure out what might be the best set up for my tank. I have designed the tank with HOB equipment because my sump is in NC and won't be here until the middle of May. I'll probably be trading it or selling it to get LED lights because I don't want to run another overflow box (can't sleep at night). Anyways back to the question..I have modified an AC70 into a refugium. I have an AC20 impeller now to lower the flow and have attached a 21 led refugium light to keep Chaeto in the box area. That was what I originally planned to use to remove phosphates etc. However, the more I read up on different reef builds, the more I'm starting to wonder if I made a poor choice. I'm thinking about running the "poly-filter" in the AC70 now and the Chaeto as well, if it will grow with the filter pad in there. What do you guys and gals think? Should I purchase an HOB reactor to run GFO and Carbon or do you think that's overkill on the 20G? As usual I'm overthinking this mess and will probably be fine with poly-filter and Chaeto. Thoughts? Opinions? Flames?
