The displays a 210. Turkey wings are live clams that do an excellent job of filtering the water. I don't know of anywhere you can buy just them. Mine came in on the live rock I buy from Florida. The whole idea of the deep sand bed is that it converts the nitrate and removes it. It does that by no air penetrating the bed. Of course the macro does the same thing. I just like to have as much removal as possible and the fact that I feed the refusium from clean water. It flows from my return pump through a gfo/carbon reactor before entering the refusium. That way I'm only removing what makes it through all the filtering, skimming, reactors rather than dumping all the detritus into the fuge. If the macro suddenly takes off I know it's time to change the gfo media. Lots of views on the right or wrong way to feed the fuge but this method seems to be working well for me and the fuge is full of pods and macros.
Very cool sump there. Think I'll do something similar w my 75 once I upgrade to something much bigger (currently use the 75 as a display). Looking at the sump, how do you feed your fuge section (I'm assuming the fuge is the far right and middle is the return)? You said you feed the fuge filtered water so just curious how you feed it when it is on the far right side (i thought that usually on sumps where the middle chamber is the return with one side having skimmer/gfo/carbon/wtvr and other side containing fuge , the skimmer section and fuge is fed by water straight from the overflow, with the fuge section having a valve to lower the flow)? Again just curious, thanks!
