Well I guess I didn't totally understand how a wet/dry system worked and made a mistake in my sump design. Problem is that it's now got a 75 gallon tank on top of it and is only accessible from the back to do the work needed to fix the issue.

I used a series of tubs. My initial plan was to try and make something inexpensive. Things don't always turn out the way you plan but in the end I figured I'd have something that was more robust than a $150+ canister.

Anyway, first pic is how it currently is. Second pic is how I plan to fix it by placing another medium sized tub in the large one (already have it, already know it all fits). The light blue is my mechanical media and the green is the biological (I'm using loofah sponges I got 2 for $1 but I plan to supplement them later). My question: Does this look like a good fix?

The crappy part is that I have to drain the tank a bit to move it. I figure I can still move it myself with 25% water left in it (I am strong) so hopefully the fish will only be moderately stressed.

Right now it's not running, I'm using temporary filters (a ****ty HOB Biowheel 330 where the stupid wheels get stuck) and a Fluval submersible, largest they have.

I would try and get the media out of the water all together. Some people like their media half submerged, but I like the old way. Wet then dry, all the way out of the water. Let it run through then out.

The design looks good though.
 
Hmmm, not sure I could do totally dry right now, I am limited on height, it's maxed out. I'd need to rethink the entire thing to do it. I think the Sterilite drawers could work for that with my setup though. I'm new to this so I didn't know exactly what would work. I thought I was copying someone else's design. The second diagram accomplishes this but the first (current) wasn't exactly right.

I'm quickly getting obsessive here.

I put sliders on my 75 before and it work like a charm for me;)
 
Well maybe this is a better question for the Filter forum but how much less efficient will my bio-filtration be if it's fully submerged?

I really don't want to drain my tank almost entirely.
 
I don't really see the point of the extra tub. You could just cut some holes in side of the bottom most tub in the first picture. Make them low enough not to submerge your media. IME scrubbies work well both ways. I have about 15 g dry and 5 submerged with my 180g, and an xp4 with a bunch of them in it on my 75g.
 
I don't even know if I can get the tubs out that are already in there to drill the holes. The stupid stand that came with my tank is just about worthless. The ultimate solution is probably a new stand and a new sump setup that is actually good.
 
Don't run the media dry, a 1 hr blackout will kill everything for starters.

Nitrobactergrows better in water.

As long as you get full water circulation thru the media (like second drawing) your good to go. In the first drawing water won't flow thru, just over.

"sliders" Plastic or metal disks placed under a heavy objects feet to help it slide in the floor.
