MY drawing sucks but will the flow work. That is from the top of that first pipe over japanese mating donw threw the pipe and exit the top of the bio balls filter barrel?

Does the pipe need to be lower and do an up flow because of water pressure or will it work this way.

I was going to put a pipe at the top to have down up flow in one barrel and down flow to the other but i want the pump to not run dry if the water drops 8" inches!! since my pump is after the filter.


eeeeeeeeeeer! i can post my pic!
anyhow does it matter where you put the pipes in a 55 barrel filter ? from the top of a barrel that goes under the same barrel to the bottom of the next but the flow exits the top of that barrel with some holes further downhe pipe to adjust for water level?
