hammons.david Posted December 25, 2014 Share Posted December 25, 2014 I am currently running a 350 marineland filter on my 68g. I would like to get a hang on the back refugium and take off my 350. I know I will loose mechanical and some chemical filtration ( but I can put a bag of carbon in the refugium ), but the benefits of a refugium will be awesome. I was just wondering if I could only run a refugium as my filtration. Link to comment Share on other sites More sharing options...
Timfish Posted December 25, 2014 Share Posted December 25, 2014 Yup, and it doesn't need to be lighted either, read up on Tyree's Zonal system he uses for his coral propagation (it's also skimmerless). And keep in mind corals are pulling ammonium, nitrate and phosphates from the water and IMO should be considered an essential part of the biofilter. Here's a video of a "fliterless" system I maintain: Link to comment Share on other sites More sharing options...
hammons.david Posted December 25, 2014 Author Share Posted December 25, 2014 I think I will get a under the tank refugium instead. Do you have a drilled tank or not? Link to comment Share on other sites More sharing options...
Timfish Posted December 26, 2014 Share Posted December 26, 2014 Yes, most of the systems I maintain are drilled with internal overflows and sumps/refugiums. I actually prefer a system with as big a sump as I can get but it is by no means necessary. Link to comment Share on other sites More sharing options...
hammons.david Posted December 27, 2014 Author Share Posted December 27, 2014 I got a 20 gallon refugium and I got a overflow box too. I think I will put cheato in my refugium. What macro algae do you use for yours. Link to comment Share on other sites More sharing options...
