Which Tunze Skimmer should I buy??

[ncny21802]

I considering getting rid of my ASM G-3, even though it works great, and getting a Tunze skimmer because of how much room it will free up in my sump. I currently have a 125 Gallon tank that is heavily stocked with fish and corals. What would be the best Tunze skimmer to get? I'm thinking the 9015 but Im not sure.

I got 9010 and it's great I have it inside the tank and there is no bubble.
