130d skimmer

Hello all I am currently running a Tunze 9001 skimmer in the back of my RSM130D, but am really after a skimmer that surface skims. I know a lot of people run the media rack and tunze 9001/9002. but have taken out the media rack and am using a canister filter for running my mechanical filtration...

Hi guys! I just bought a RSM 130, it has upgraded pumps, beyond that it's stock, I want to upgrade the skimmer however the suggested models are discontinued, any ideas on good units? Also other recommended upgrades. Thanks!
