Ok, but not great. By Joe on 4/11/2012
Joe wouldn't recommend this product to a friend
I purchased one of these to put a Tunze 6055 in a rock pile to help with circulation. Although the pump fit perfectly into the product, the fake rock would not sit in the rock pile in a way that pointed it the right direction for good water flow. The rock is basically a tripod that points the stream upward. I needed the stream sideways and there was really no way to do this in the rocks I had. Perhaps I will use it in another setup, but IMHO, this product could use some re-design. Pass on this unless you have a very large tank that can handle an upward stream flow.
