Hi everyone -- I've posted on the forum a couple of times. I'm in Northwest Georgia in the US. FINALLY going to build a pond after about 20 years of wishing. My budget and my physical space will only allow a small pond. Probably 6 feet x 4 feet, with a little waterfall. I know that larger ponds often make for a more independent, low maintenance system. Smaller ponds are more easily thrown out of biological balance. I'm going to be using a liner, rather than a preform. Wondering if all you with small pond experience would care to chime in. My hope is for a small, natural-esque, rock pond to attract frogs, birds and to house a small number of goldfish. Looking to go inexpensive (although I know your most important expenditure should be a GOOD liner.) Wondering what sort of filtration system I should use, considering that the pond will be small. I would welcome and appreciate your thoughts!
