Hi, not sure what is going on with my duncan. It was in a biocube for a years or so, then we moved it to a 75 gallon. The 75 gallon was a combo from the biocube 29 and a nuvo 40. Most of the live rock and sand came with livestock.
The 75 is in it's 9th week of running. Parameters are all good with the exception of high nitrate level of 20-40. Hard to read, but consistent from the smaller tanks. The first month was great and the duncan really reached out. Last week I noticed 1 head was closing up. I moved it to the other side hoping it would like that location better. Now that head looks dead and another closely behind.
Any suggestions?
