As many of you already know. I am going to upgrade to a larger tank. I am pretty Illiterate when it comes to wet/dry filters and sumps. I was wondering, do i need to have a wet dry and a sump, a sump by itself? or the wet dry by itself. Do sumps work as a filter in itself? I was flippng back and forth between a 135 gal, 150 gal, and a 180 gal tank. I know if I get the 135 or the 150, I am going to be regreting it later so I am leaning heavily toward the 180. I know us guys have a compensation with size (hahaha). (I know thats pay back for calling Bifferwine by the wrong name). What do you guys think about this. Let me know. Is a sump more than enough. Another question, is how big a sump to put? Glasscages recommends a 49 gallon. Is that sufficent? Should I get a sump from somewhere else? I gonna be using some of my tax money to finance the upgrade. I am going to have a budget of about ,000 for the tank and sump.
