My Tank Thread
Several of the brutes were filled 2/3 or more full of largish rocks, so a powerhead at the bottom would probably stop working and I wouldn't know it. But it is a legit concern, and I cannot remember exactly how I dealt with it, but one way was to deliver the water near the bottom and remove it at the top.
Even if the water entered through a bulkhead near the top, the water was channeled down to near the bottom with PVC internal to these rock filled ones.
The two sumps has a lot of flow and no rocks, so there was no concern with them.
