Hello....the UGJ's are a great idea. I would go with a reef ready tank so you can use a wet/dry. If you go with a diy wet/dry and UGJ you should be able to do both for under 300.00 bucks that includes both pumps and all the stuff to build the wet/dry and sump and the pvc for the ugj.
PM me if you need any info on doing this
