Hi all, as some of you know I just recently purchased a RTCxTSN who is about 3.25" head to tail. I am now starting my build for his pond. The plan? I have a 12'5"x9'4" pond liner which will obviously be where he will swim around in, since I live in upstate New York it gets very very cold here...this pond will be outdoors which presents numerous problems, which I have found ways of fixing. To keep it warm during the winter months there will be a polyurethaned plywood box to go over it this box will be lined with fiberglass insulation to keep the heat in and cold out, much like a house. The pond itself will have a decent sized pond heater....not de-icer...actual heaterm to keep the water warm obviously. For filtration, I will have 2x 4 tier "closet organizers" filled with scubbies and biomedia, run off a single pump. There are still some bugs in the plan, but I will figure them out and it should be operational by end of july. Let me know what you guys think of my idea...as the build begins within the next couple of days.
