Hi to all, I have a 100 l marine tank which has been runnung for a year now. Two months ago I have installed a sump/refugium with a six inch DSB and topped with live rock (I have used playsand).Reason for this is that I like to have a NNR. I can see some activity in the refugium, like amphipods, copepods, bristlestars etc. After five weeks I began to see worm activity at the top of the DSB.
My query is how long will it take to cycle the DSB and begin to see some N2 bubbles which means that the DSB is working as it should. Also I am not sure if I have used the correct sand. Any one can help?
