6255 behind false wall?

[acesq]

Roger, do you see any issue with hiding a 6255 behind a false perforated wall at one end of a tank, with just the snout poking through? Will it work as well? I'm trying to come up with a way of avoiding a closed loop system (and the associated cost, maintenance and generally lower performance) while not having to see the powerheads. (Spouse requirement!)

My only concerns are as follows-

1) You will need to have a very high flow rate to supply the pump, it will pump out much more water from the compartment that a typical sump drain for example so the intake needs to be suited to that.

2) You will of course lose the ability to angle or move the pump

3) Their will be more noise from the hard surface to hard surface contact and the back will need to be supported some how so the pump does not separate in half. Ideally the magnet holder would fit in to hold it as well.

4) Their should not be a drain in the same compartment as in a power failure water would drain through the pump so the safety of the overflow would be defeated.

Thanks Roger. So what you're trying to say is its a piece of cake! Lol. All good considerations.

I imagined a false wall sitting approximately 4 -5 inches (far enough to fit the powerhead and clamp) in front of one end of the tank (the end dimensions will be 32" wide by 30" tall) under the overflow slot for the external overflow. The wall will have one or more holes slightly bigger than the diameter of the snout of the powerhead(s) (I'm thinking (2) 6255s), will have numerous slits for water flow and will terminate an inch or so below the waterline with some sort of guard to keep critters out. I'm losing tank space for sure, but it may be a necessary sacrifice to keep the tank as clean looking as possible. Do you think it will work?

The pumps will need to be at least 6" below the waterline to keep them from vortexing in air and producing bubbles. I also worry about the pumps sharing the overflow with a drain, while you could pull it off with a stand pipe, you will have to be careful that the tank cannot drain down to the lowest point of the pumps and flood your sump in the event of a power failure.

I will be sure to keep them at least 6 inches below the water line.

They will not share an overflow, they will be inside the tank, the overflow will be external.

Whats the stop fish going behind the false wall?

Gutter guard or other type of screening will keep fish from swimming over the top of the false wall.
