i am going from that set up that is beautiful for plants, which would be awsome if i was into plants, but im not so much for plants and more for fish. plus i have dogs and kids that like to get into the pond and swim. right now with rubber liners i have to worry about springing a leak. i am changing it to one giant concrete pond without all the plants so it will stay clear and my dogs can get in and swim and so can the we. i will be using the good old burried 55 gallon drums for my filtration, filling atleast 2 with nothing but fishing line, using the supplied threaded holes and pressurizing them like a canister filter. possibly using one full of sand and then using my 275 gallon bio waterfall tank behind a rock wall for the final bio filter. i will be checking into uv filters and more than likely using atleast 4-5 36watts. I dont plan to slack on the filtration, with how much it is going to cost me to do the concrete and then seal it i might as well have the filtration to back it up and make it monsteruous. i also might be getting a heatmore and laying copper water piping in my concrete to keep the pond at 50 degrees all winter while the temps here are well below 0. (heatmore will also heat my house, garage, water heater, and indoor pond aswell.)
