IF it was me and the thing is gonna be off the ground, I'd put a big ol drain right in the center on a ball valve. 3" would be ideal. Would be much easier to clean. With a 1.25" it won't be enough of a rush to disturb the sediment, especially being on one side of the tub.
I'd also figure out how to add air to the bottom of the scrubbie racks. A way to secure it to the bottom of the tub so the air stones/bars don't float when you put a good deal of air to them, but it can't be permenant cause air stones/bars/discs plug up and will need to be changed.
I'm only making these suggestions cause the design is very similar to the first big filter I made. I know there's several improvements I made over the years to mine till I got to the point where I couldn't think of anymore.
I'd definetly put a plugged bulkhead in there somewhere. Eventually when you upgrade pumps, and want the reliability and efficiency of an inline you're gonna need somewhere to plum it into. A capped bulkhead fitting would be ideal.
How much weight will those racks hold? Sturdy enough to sit a bio reactor on top? If not, I'd brace em up to hold it or fab an insulated lid you could sit it on.
Anyone who thinks this isn't the funnest part of a raytank suffers from a lazy mind. Designing a system that you can NOT find improvements that can be made in is a challenge for any raykeeper, and the best way to do it is exactly what you're doing. M,any minds are better then 1.
