Help on sump plans

[N3hihz]

Hi all,
I'm planning on building a sump with a 10G and a 20G H tank

So the first issue I see already is that they're not exactly similar LxW

Here's a draft plans I just sketched. No sized248937

My plan is to drain down into the skimmer chamber ~75% and have a split that drains ~25% into fuge installs in the corner of the 20G that will go into my 10G tank where the propagation chamber will be then into the return chamber which will be pumped back into the tank or maybe adding reactors here. Not sure yet.

Lmk what you think or any ideas. Thanks

You can have a look at this build if you like, if built correctly it will account for all of the nitrogen cycle.
