Hey,
i have always been a sucker for ponds so i have decided im going to constuct 2 new ponds, the first pond will be built with a nice garden and BBQ Area filled with Koi,
The Second pond will be built inodoors to house my Fresh water rays once i get some, the pond will be about 50-80cm deep about 2-4 mts across 3-4 long the big question is heating it, with out dying from the cvost of power.
Cheers
