Headline: WHAT NOT TO DO WITH YOUR YELLOW PERCH GROWOUT SYSTEM.
Last night I was draining twenty gallons of water out of my home growout tank since this system doesn't have flowthrough capability. As I was draining it I turned on the sink hose to simultaneously fill. After about ten minutes, one of my perch suddenly shot to the surface and jumped about two inches in the air! "That's strange", I thought to myself. In a little bit he started swimming upside down. It was at this point that I realized I had stupidly turned on the HOT water nozzle and the temp in my tank had gone from 65 degrees to 85 degrees.
I quickly turned on the cold water and was able to return the water to normal with only the one mortality.
Hey, I told you before, I'm no Alfred Einstein.
