I feel real dumb asking this but....

On my AC500 and 300 filters, I got 2 of the same pieces for the uplift tube thinking that maybe one was just a spare. But once my brain kicked in I figured out that maybe for deeper tanks you can hook the 2 together.

So now my brain is picking up speed and I started to wonder - is it better to have the uplift tube as close to the bottom of the tank as possible or is it better near the middle of the tank?

I prefer to have it closer to the bottom--that way more waste is picked up before it can hit the bottom. Of course, I have powerheads that angle towards the pick up as well to increase the odds of wastes being captured.

I, too, have the intakes of my AquaClears closer to the bottom than the top.

I have 3 aquaclears two draw from the bottom and one midway they don't seem to make much of a difference to me but I would have them all sucking from the bottom but my yellow lab love to bury the intake tube so one is up midway. I would have to say try to get it down if you can but if not midway would be fine....just my 2 cents
