Great info, thanks Oz! This seems a lot like rocket science - only a little more complicated!
One thing I'm having a hard time understanding - which has been touched on in this post by someone else - is how to get the water down to 55 without killing them. They'll be coming out of 80 ish degree water, so I assume you start out with 75 degrees in the tank, and lower it slowly as to not stress them?
Thanks Oz for all your expert advice. I know its gonna pay off!
