This is my idea. Already have tanks to be used. The 20gl will hang directly under my return (still thinking of a way to hold it so I can take it out and clean it when I have to).
My biggest thing is I like how my 60gl sump is right now... 40% media and the rest free flowing water for grow outs (in my head its perfect after my 1 month Prazi bath for new fish, so they are in water with a great amount of movement to grow a lil faster
I need feedback... Pros and Cons

(forgot the sponge on top of the 100% submerged ceramic rings. 1 drip plate for the Bio Balls and 1 Drip plate for the Rings)
Also, Drains from 20gl to the sump will be 2"Dia and drain from 300 is 1.5". This way that should never be an issue
This is what it looks like now...
