I've got a pair of Tunze 6045's right now, and they're just too powerful for my 40 breeder. I'm looking at replacements. I'd love to go with an MP10, but I'm not paying $250+ for a powerhead. I've been comparing the Koralias and the JBJ's. I can't seem to find much info on the JBJ's. Anybody here used them? I'm looking at the 500gph combo from here. Any thoughts on these would be appreciated.
