Thanks again all. Finally moved the big silver into the 240. What a pain in the arse. But all went well..no lost scales and no trauma. Thank god I have a koi net.
He's roughly 15" now...and going strong. He looks so happy now in the big tank...longer swim length.
Still didn't get a chance to install the FBF...but I did plumb in my UV turbo twist, and install my crestron control equipment to control the tanks pumps, lights etc...
Today is another day...hopefully after work I'll get to it.
