Yea that is a great skimmer.....or look at the Aqua-C, both probally one of the best...just remember whatever skimmer you get, make sure it turns your tank at least 4 times an hour. This will keep your tank water super clear and very clean, keeps the alge down also.
So you have a 200 gal tank-you will need a 800gph skimmer...Hope this helps...Chris
