Cheap Jebo 29 gallon that my friend sells wholesale. Paid about $50 for the tank, hood, and 70w PC lighting. Ther eis no built in filters, more like an all-glass tanks starter 10g than a JBJ type bio cube. I added a AquaC remora skimmer to the back. I also have a Marineland 350HOT canister around to polish the water if necessary. I'm hoping to get a local acrylic builder to make me a sump and fuge. If so I will be using my Euroreef skimmer on that 29g. My plan is to build a 20g fuge that the water will flow into and it will be on a shelve just under the tank. the water will flow down another tube into a 20g sump with the skimmer and a nice Eheim return pump. That way I can also add about 20g more water to the system ro keep it stabilized. Right now there is 5g of cultured live sand from a previous tank and about 10lbs live rock.
