I love to dive, I just have developed an adversion to wetsuits

Winter diving that is.
Lake Park is right across the Florida line on I 75.
If it is a pond in a greenhouse I would suggest a pool heater. There are a few Gardening boards on line that have people who are very much into ponds that would have some good advice on brands of Heaters.
My wife is my dive partner, but we can always use some more people.
I am not sure if you know the area well but there is a rock reef not a hundred yards off shore just south of you, most of the time visability is 5 - 10 feet but it does clear up. 5 - 10 feet visability is kinda a sweet when your looking for bugs.
Look for Wabasso beach just south of Sebation inlet, you will not see any mention of the reef, but it is there. Straight off the boardwalk.
