JD, hey buddy I would get like a 10 gallon nano and start that little puppy or even better I would do a very basic 20 gallon right now with no sump and when you move you can get your 75 set up and use the current 20 as your sump and you allready have good live sand and LR to start the cycle with!!!! That way you still have a little ocean in your place now. That is how I would do it but I hate to wait for stuff.
good luck buddy keep us posted.
