Marineland Emperor Bio-Wheel 400 Power Filter

[Buffy]

I have this installed. It comes with an extension tube with middle slot adjustments to filter middle of tank.

I can't use the extension because when installed it lifts the filter off the bottom of tank. My tank is too short for it.

Tank is 21" high including 1 3/4" black rim. (Bottom of rim is my waterline).

I don't have enough sand yet (40lbs so far), I want a deeper sand bed. So that will decrease the "height" more.

Question 1: Is the middle slot holes needed?

Question 2: If so, then how can I cut the plastic tube to fit so I don't shatter it.

Question 3: If so, what size?

Question 4: I'm seeing people having more than one, is this necessary?

I think I'm gonna run out of tank rim to place things.

I do not know how deep to go with the sand and I also need more rock but I will do a different thread for those. I will be going to foster and smith's tomorrow.

Thanks for any advice, comments, suggestions and opinions.

I used a hack saw to cut mine.

Same here, the middle attachment is just used to filter all levels of the aquarium

Thanks, I actually think I have a hacksaw somewhere in the garage LOL.

How far above the sand bed should the bottom of it be? Touching it or no?
