I am curious if it is a good idea to have a wet/dry trickle sump along with a seperate refugium for a reef tank. would this be overdoing it or would it be all the better to keep corals thriving? i know that a good wet dry can sufice with a good protein skimmer and that a refugium can help to level nitrate/nitrite levels. so im thinkin a combo of both would be good. what are some thoughts?
