Submersible pump

[rykna]

I need to replace the pump on my AquaClear 70. My submersible Fluval pump has the same gph as the aquaclear. The pump on the AquaClear is not submersible. Can I use a submersible pump with out submersing it?

Never mind....just remembered why that wouldn't work. The submersible has both a intake and return flow, the pump on the aquaclear doesn't.
