I currently am using the AquaClear 110 (was the 500). It's doing a very good job of keeping the water in a 40-gallon stock tank clean, and I don't use an extra extension tube with it. Having the intake lower would probably help, but no filter is going to pick up all the crud in the tank, although, there is very little, if anything at the bottom of my turts' (turts could be helping, I don't know). If you're looking to find a filter that will pick up absolutely everything, though, I doubt you'll find one (if you do, let me know, I want one).
Do you have an older model Aquaclear? If so, the filter was recently repackaged to include bio-media (Bio-max), which you can buy separately. I'm using exactly what came with the filter when I bought it not too long ago--the sponge, the carbon (which should be replaced at least monthly in the 110) and the Bio-max.
I think you said you're using the Aquaclear 200 in the 30-gallon? This is too small for the tank. I'd get the 110 for it. BUT, if the tank is too small for the size of the turts you have, any filter is going to have problems...
