I am literally in AWE!!! That is one of the coolest things I have EVER SEEN!!!
Can you imagine!? I wouldn't do it just for the cleaning aspect. It would be TOO much for me. You would have to be pretty darn devoted. I wonder where on earth he got all of those commercial supplies?? Any idea??
This just shows what possible with a bit of money, knowledge and determination. I plan to start something EXACTLY like this, with a few large sumps, nessecery heating, some handy-man help from my dad, and with quite a few rays!!!
