I have an old hottub that i am turning into a above ground pond. I have it set up for the winter to get it going strong. I put 8 feeder goldfish in it to see if they will last, it has bee 2 weeks and they have. Does anyone have any ideas about how to turn this into a nice above ground pond for fish/ plants/ and mabe a turtle? It is 14X14 34" deepest part, 18" average depth.
