Where to get a HOB Refugium

[intarsiabox]

There are lots of threads out there about converting Aquclear 110's into HOB cubes. Hagen also has a HOB fish breeder that uses an airstone to pull water from the display tank into the breeder with a gentle flow and no chance of shredding pods in the impeller of a powerhead. It comes in different sizes and is pretty cheap. There are lots of commercial ones as well such as CPR and Eshopps but for more money.
