Any numbers on optimum flow rate, circular motion like in rpm or feet per minute measured from a fixed radius for best results?
What'd think I am an engineer or somethin'?
15 to 30 cm. per second for optimal bottom cleaning.
0.5 to 2.0 times the fish's body length per second for best fish health.
http://ag.arizona.edu/azaqua/ista/ISTA7/...nk%20Design.pdfAll the same stuff in Timmon's and Ebeling's latest recirculating book. (The green one).
I have the yellow book, that I don't know where it is at the moment.
Both those guy's use my media from Denmark. I bought it from AST where Ebeling is associated with. Didn't know that till after the fact tho.
Also, tried to find the green book, but why would they change colors, as it was well known as the "Yellow Book".
My memory may still work at times
