How many fusers do you have? First thing I think of is your size of pond and how cold it gets their. If I were doing it I would put 2 fusers together and divide it out in 1/3 lengths and have 3 stations to cover more area. Or if your only using 1 fuser but do the same thing.
If you can afford it... I would put in as many as you can handle. lol in about that 3 to 4 foot depth. Keep that baby opened up!!!! If you can do that then your on your way I think!!
