Oh boy.

All I can say is from personal experience. I started out with a DSB and ended up sucking it all out and going BB. Not regretting it one bit :-)

Beyond that, I know nothing about plenums. Sorry!

In my new tank I went for 3/4" of sand just for looks. I plan to syphon it every water change just like a BB tank. After doing some reading it turns out DSBs cannot be properly maintained in Canada where the in-fauna is unobtainable.
