Well, Mojo, I have decided to honor you with the Bucket Award.

My wife says that if I am not lookin at red and white fish I'm playing with big buckets.
There is a place in St. Pete with a ~400gallon display/sale tank using only a patented, flushable, downflow bead filter in a 30 gallon cone bottom tank. No show winners in that tank, but a messa fish.
The way you're doing things makes me very nervous though, because I am trying to graduate from small "miracle" filters to full size conventional filtration, DIY or not.
You had test confirmed KHV? Or anecdotally observed?
