thank you all, I may be going another route I suppose. I see the video of David Saxby's tank on youtube and I druel all over the place. i would like to do something similar. If I was to plumb the tank into my garage i was wondering if the heat from the garage would be a pain? what you guys think? it gets pretty hot here during the day and I break a sweat in my garage with door open just standing in it. I would say upper 90s anyway. I have alot of thinking to do.
