Wow, what an exciting background. I have always wanted a Koi pond, though I have some really large Pine trees I need to cut down first. Pines are very dirty shedding needles everywhere, which are acidic so it might hurt the water quality not to mention I would always be cleaning it.
In the future!!!
Dove once with my wifes cousin; She lives in Key Largo, Fl and she used to be a PADI instructor. Still has all of her equip, but has moved on to another business project. My wife and I went out and explored the John Pennekamp State Park Reef and went out to the Dry Tortugas for a day. Absolutely loved it. I had been keeping a Reef Aquarium since 2002 and knew many species of Coral and Fish during our adventure. Can't wait to do it again.
Well onto the Aquarium your setting up.
