I have this small acrylic frag tank for sale. it is 20x16x9.5. it comes with a stand and new Black Box LED light (i've only ran this unit for a couple of days). This tank was plumbed into my DT and I just took it offline two days ago. It has internal overflow with 1" drain bulkhead (thread x thread) and 3/4" bulkhead for return. I'll post more pics tonight. It has served me well and was capable of holding a good number of frags in it. $200 for everything.
