powerhead

[cono]

I'm looking for a little bit of flow from my back wall to the front and was wondering if anyone has any suggestions ....the flow I'm looking for is around 200 to 300 gph ...the thing is that it has to be able to be secure on thick glass as it's for a 180 ...... Because I created a runway cavern and want some flow to go threw it

Given the cavern style you have, you might want something with a narrower, more directional flow. Look at a Tunze power head.
