Im renting a house, it's much easier to get away with a leak when I'm in tile and no one living below you. I've already gone through a leak. And landlord never even knew.Haha is it considered staying under 20g if your display is 20g and then you have a 20g sump?
Or is it a strict 20g total volume in entire apartment type of rule?
edit: Check to see if your state/province/municipality has its own bylaws regarding pets. Where I live most rental agreements state that there are no pets allowed but it's actually illegal to enforce this if you're the landlord. Nothing specific stated with regards to aquarium volume/weight though.
And I think it's per tank not volume.
