Hi everyone, Currently I have a 60gal cube, so small tank in your world lol, I currently run the Apex Jr. Only had it since February. I recently maybe have the chance to acquire this unit, just the brain by itself, for not a lot of money as I do not have a lot but could buy this unit alone as a building block. Would it be worth to get it and replace the Jr with? Or will this be quickly obsolete. Is everything compatible with this as well?
