Would swapping the intake strainer and connecting the aquaclear input pipe to a submersed pump be a viable way to have a self priming aquaclear HOB filter? I think the marinia slim does this by default. Has anyone tried or considered this?
For just jump starting the filter or for full time use?
Using a 'pre-pump' would put too much flow through the filter, causing it to bypass I'd think. Aquaclears should self start themselves provided the filter itself is full of water. I know they will backflow themselves into the tank when you have them turned off during water changes.
The only HOBs I've had that will actually re-fill themselves, prime and go are Aqueons and Seachem Tidals. I still would recommend AC over either.
