I have a 120 and 125 gallon tank that I would like to put on one filter system. How do I go about doing that?....................Any Suggestions?
2 Tanks on 1 Filter

make sure they are the same height
connect them below the water line with a pipe to make sure the levels remain the same.
split the intake and returns add a valve on each return for balance control

Seperate overflows and returns from a seriously big sump.
I dont see any reason why you couldnt use a single sump as long as it has the bio capacity for both tanks, as well as an internal liquid capacity in the event of a power failure.
My preferred LFS uses a huge tank for its filter system. Most of their tanks overflow into a common drain, then they are all fed from a common pump (ball valves at each tank to adj return to each).
It seems to work well for them but I assume it can be a bit of a headache regulating all of those valves to get everything initially setup right. In your case, using two pumps, rated for the expected capacity of each tank would be best.

Well, my first idea was to use one sump with two pumps, but I thought I would be looking for trouble. Then I figure if I use a bigger pump it would work. Thinking about it I thought one would drain fast then the other any suggestion.
one sump two pumps way easier. I have two tanks on one pump I tried the ball valve and it was a pita.
This is what happens the tank on the left was filling up to fast so I closed the ball valve a little. So then the left side flow was reduced but this caused pressure on the right side and it was increased so now the right side filled up more then the left.
I eventually got ride of the valves and just made sure my stand pipe was the same height. This didn't fix the problem as one tank still gets more flow then the other, but the water level is the same.
both of my tanks where the same exact size and on the same stand so no height difference. Plus with two pumps if one goes out in the middle of the night you can switch both tanks to run off of one.
I will sound dumb but, I just now while reading my message realized I have a spare pump for my two tanks. I kept this pump in case the pump in there now dies, all this Time i could have ran two pumps and saved my self the headache.
