my theory is you can cut the rated number of the skimmer in half and thats the max it should be used on and only if it is lightly stocked. so a 280 gal skimmer would be real good for a lightly stocked 140 gal tank.
look at a bubble king add.. they say in there general print that the mini 200 is good for tanks up to 2500gal, but in the specks they state that it is good for tanks 135 to 265. I would assume that the 135 with a deicent load and 265 with almost no fish.. I would say even this one is to small for your tank, but I am not familier with the buble kings as they are to pricey for my liking, but for a deicent skimmer regular bking 200 or a vertex cone 300 you are looking about 1500 bucks. so if you can mod what you have to make it skim better try that first.. unless you can get a smoking deal on a big skimmer. Maby ask Asmodas as he usaly has 10 skimmer laying around
