Thanks for the information everyone! I told Joe about it today when I saw he had already put the MF 75 underneath. He said, "it will be fine, Amanda" with his condescending "I'm Joe, I know everything" tone. I've been on this site for as many hours as I can stay awake and maintain my mother of the year award I'm goin for and I've saw how Biff used the 55 for her sump. When I suggested using this tactic with our current 30 gal, he nulled my suggestion at saving money.
This is all coming from the man that killed our first 5 fish since I've been taking over everyone is living.....grrr!
And besides transforming into the incredible Hulk and lifting the tank myself I'll never even be able to change it!
We do already have a protein skimmer that we planned on using in the sump. Any suggestions on what to do with the bullheaded breadwinner I live with?
(and as much as I'm learning about tanks on this site, I am also learning so much about its members...all your tank envy, cleavage, & weiner jokes are crackin me up!)
