I was wondering if I have enough pods for a mandarin. I have a 40 breeder with 50lbs live rock and 70 lbs of arag/oolite (40 lbs arag/30 oolite)
sand. Plus 20 lbs rock in my fuge with coarse sponges. the glass in the fuge has about 25 to 50 copepods per square inch. And there's amphipods in the sponges everywhere. Could I just transfer the sponges back and forth from my fuge and dt to keep my population strong? I don't use phyto or anything but I do feed heavily. This tank has only been running for a month or so, but everything was transferred from my old tank except the sand so I didn't experience a proper cycle. I only had a week long diatom outbreak. Thanks for any suggestions.
