Fish room ideas? doing a shed for a fish room.

[Milad]

the buddy that made my the stand is going to help with the shed.

If I tell the city im going to attach it to the house, what will they ask for? drawings? etc? can they refuse it?

Also I dont get why I need extra heater, you guys probably know better than me but if the tank water is always 80degrees and its constantly going through the sump, etc and the shed is sealed, why would I need to add a external heater? If anything wouldnt I want to have more internal heaters?
