concrete swimming pool conversion ideas

Hi I am in Florida and have a concrete swimming pool that is the bain of my ......anyways I have seen online different ideas<salt,oxygen> to convert so u don't have to use clorine so much. In Florida we have to be careful of life threatening bact. and amobea. I would rather turn the dern thing into a duck pond but we are pushing it with chickens in my neighborhood. Any Ideas or links to eco cheap conversions?

Thanks,
Robin

look into aqua-culture

fresh water crays/ fish farming many options if you care to google. there are a few threads in this forum with links to aquaculture sites

Thank you I will!

there are a  number of people who have turned their old pools into massive aqauponic installations.

Thank you Charles. I am in the city so I don't know what the charges would be for that and wheather I could do it for a business base. We do have the warm weather though. Plus I guess I need to be able to put it all back together when we can get the house on the market sometime in the near future! 5-10 year homestead type plan! As the old song goes....should I stay or should I go?
