Habitat - Outdoor :: Submersible pond heater 400 gallon?

[justify_yourlove]

I have been looking everywhere the past month or two for a submersible heater for my 400 gallon outdoor pond, nothing at PetSmart, Home Depot, or online. Please help, brand, model, hopefully $300 max and around 200 watts if possible. Thanks!

I have 2 Visi-Therms in my 130 gal pond. Not 100%, but I believe they're both 200w. They're not specifically for outdoor use, but the pond is near enough my porch the cords reach and they're out of the 'elements'. I use a couple in different areas of the pond & it keeps it nice & warm (unless temps fall below the upper 30's - which in central FL isn't often at all!) Hope this helps somewhat...

Have you tried http://www.tricker.com/
or
Pondbiz.com
They have lots of pond supplies. I buy from William Tricker every year. They are very reliable too.

I believe http://www.azponds.com/ is a big favorite around here.

Thanks everyone. Marineland's Visi-Therm Deluxe Aquarium Heater 300 watts for up to 100 gallons on Petsmart.com (their stores do not carry it) is my best bet right now ($25 including tax & shipping). Aquarium heaters seem to warm water even more than you think they would.
