I recently installed a Bubble king mini 200 on a friends tank and and all I can say is WOW these skimmers are awesome. This skimmer takes in 1000lph of air with a 8" reaction chamber and it's foot print is only 9.25" by 9.25" by 23.5" tall, its rated for 130g to 400g. I have a really awesome connection for Bubble kings and I liked this skimmer so much that I think Im going to get a Bubble king for myself, I think I am going for the deluxe 300 external. Anyone else use a BK or have a suggestion for a awesome skimmer for a 275g sps system.
