I hear you it just might work as long as you can keep the temp down low enough and not cook them. I would hate to see a power outage and then have the unit reset to 102 deg. and have you come out and have some nice cooked fish \:D Or if it reset and the blower came on and the fish were on the top surfing the bubbles. But if you left the jets on low with a little air, you might just have something there.

Maybe I will tell my wife I am going to do that unless she spends more quality time in the hot tub with me. ;\) \:D
