As said above.
I do not think water fall is critical if you have other means to oxygenate the water..

Exactly. Not sure if it's necessary if your return pump has enough flow. Maybe even use a spray bar.As said above.

I have the first chamber where the water drains to with 3 x 24" long by 10" wide by 3" thick sheets of jap mat that are washed monthlyYou must be rinsing lots of jap mat if that is all there is to trap the big particles. Why not filter socks and then jap mat? I have big sumps and no waterfall effect in any chamber and it still works really good, probably couldn't ask for better except for maybe a machine that would change the socks for me! LOL
Interesting thread.
I find we talk about sumps far too little, i've never been happy with any of mine, i just cant find a design that works well for mechanical filtration, for instance T1 in your sump how do you remove your first chambers jap matting without all the poo dripping off back into the water?
In which case youve just caught all the debris and then it's fell back into the sump to be pumped all around the tank making it cloudy.
My middle chamber containing my bio media is caked with crap.
I too find the jap matting cloggs quickly but at the same time far less than other materials, especially filter socks which have been washed.
I've thought for future reference i want some sort of floating bucket container that is stacked with mechanical and water merely trickles through it but it's not submerged - this way i can just remove the container, wash everything and install it back but as it's not submerged the muck won't seep into the water.
Also, what's the relevance in that video where they put like legs between each sheet of jap matting.
