Sumps will work fine with planted tanks. You will need to do a little work on getting it in the tank though. A reactor,Mazzei injector or needle wheel pump will work fine.

Get a nice misty froth of co2 mist in the tank and you will be fine. The hard part will be the 30" depth. That will be a bear to scape and work in, but nothing a good set of long 24" tools cant fix.

The best of luck to you!

Regards,
Orlando
