Best Way To Filter & Heat

[zmazza_55]

What is the best way to filter and heat an indoor pond? I found some plans to build a 600 gallon plywood one. I'm wanting to build it when I purchase my new house in the next few months. I'm planning on putting it in the basement, so it should be going on a concrete floor. I've seen Ocean Clear canister filters advertised, and they look like they would work, but I'm not sure. I'm really at a loss for the heater, though.

I would suggest putting some styrofoam board on the floor (under the pond). This will help with the heat bill! I would build a wet/dry type filter and place the heaters in the sump. you can go with multiple titaniums, or buy a commercial type submersible heater.

i am thinking of using a couple of waterbed heaters under my new liner pond to help heat it on my others i just use regular heaters or inline heaters
fir filtration i built my own and it was way cheaper than buying one and it works great
