Magrath, you got a bet on that. I just got certified for advance open water, Nitrox, boat, deep, and working on night. Looking to get certified by late next year as a dive instructor...so I need the dives as well. Snorkeling will be fine too!
Debating right now about the sand to put in. Jeff used pre-washed sand when we did his set up and down at Torii because it was rinsed out with fresh water, killing everything nasty...I can just seed it with someone's estab tank and wala! I'm thinking about making water for the first batch as well, though Deep ocean water thru a micro filter will work as well. Thats alot of water though and wil need some help getting herre. But that's in the future for right now..Still doing leak tests, etc....
