My husband is wanting to take one of the rooms in our basement and turn it into a fish room. We have a 90 gallon with a 40 gallon sump and also have a 55 gallon that is not set up yet. Our 90 gallon used to be a saltwater setup but we are changing into a freshwater using the same setup. I like that idea of having the sump so that you can keep the main tank a lot cleaner and do the water changes from the sump. We also have the ro/di system and will be attaching it to the tank for automatic top offs.
I can't see pictures of your setup right now because it states that the picture gallery is under maintenance.
