I was wondering I am getting a really tight refugium sump and the refugium I am getting has I belive 4 little dividers sticking up like 3 or 4 inches in the refugium section. Telll me wut u think. In the first two have the normal refugium stuff. Then in the next one have that little section dedicated to growing my yellow tangs food. (algie and sea weed). Then in the last section have mangroves. What do u guys think about mangroves and what can u tell me about them. Also of course all of the sections will have mud. I might also throw a crab and snail in too. So all feed back will be great. Thanx.
