What does the wet/dry look like? Like is it a bought one or one converted from a tank? What other equipement do you have on your tank? A
skimmer?
If you have a skimmer and plenty of water flow and
live rock you could get rid of the wet/dry and convert it into a refuge. Wet/drys are not used much now days since most people think they become a
nitrite factory after a while. I think a refuge would be more benifitial then whatever the wet/dry is doing since it will have a wide range of life cleaning the water then just the bacteria that is in the wet/dry. If you don't want to get rid of the whole wet/dry you could just make the wet/dry smaller and make part of it into a refuge.
Post a picture of the wet/dry and we can come up with better ideas of how to help you more specific.
