This is my G/F's pond. I am guessing its about 1000gals, 10X4X3. It has several HUGE Koi, and some goldfish. There are 3-4 Plecos in there, but I have never seen them. It was here when she bought the house. I tried explaining to her that fish need oxygen. Its a choice between being "Happy or Right." Well, since I have absolutely nothing to do today, I tried my hand at a DIY filter. She was currently using a shoebox size chamber, 1/2 was a UV chamber, with a bulb that has never been changed, and the other 1/2 was a piece of foam. Thats it. Well, my set-up has been running about an hour and I can see a difference. Let me know what you think. I plan to add a UV filter as soon as Lowes has them back in stock. Plus I have to change the arrangement. This is just a temp "emergency" set-up. It will go back behind the waterfall soon enough. Also, I plan to raise the pump, and get the return below the surface. FL doesnt have too cold of winters, but I figure every bit helps. Also, I have a tank set-up in the house for the Plecos, as soon as I can see to catch them.
