I previously had the skimmer on a 95 gal tank not exactly sure what its rated for to be honest with you, but is is beefed up with the sedra 5000 (also throwing in the origional 3500 pump as well).
The ballst is exactly like this one...

comes with all the waterproof end caps and in origional box - brand new. Also has 2 seperate on off switches if you want to time the bulbs seperatly.
