The Tunze Nanostream rock is one of the accessories that make Tunze pumps so easy to work with. Primarily used to hide Tunze Nanostream powerheads but can be used to position a pump on the bottom of a tank. Made of white ceramic stone and suitable for fresh or saltwater applications. Works with Tunze Nanostream 6025, 6045, 6055 powerheads.
Ok, but not great. By Joe on 4/11/2012Joe wouldn't recommend this product to a friendI 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.
