I plan on building a 3400 gallon pond outside. The filtration im looking at is the ultima II 6000. I will be having rays and aros in this tank. Will this filtration be sufficient or should i get the ultima II 10000? FOr heating, ill be using a 1500w titanium aquarium heater and for a deicer ill be using the thermo pond 3.0. I live in north new jersey where temps in the winter range near mid 40s to high 20s. Would the filtration and heating im using be sufficient to run this pond year round with no problem?
 
Tough questions. 1500 Watts is inadequate for heating an outside 3400 gallon pond. You should probably seek advice from pond experts. Many fishkeepers move their fish inside during cold winter weather. Heating a large outside pond for tropical fish might be costly during winter. The outside pond experts would the ones to ask.

i see, do you know what type of heater can heat a tank like this
 
I'm in jersey aswell.. it gets way to cold to heat a pond/pool to 78-82F in winter imo. It would need to be ina garage of some sort. I'd personally do an indoor stock tank.
 
Your best bet is to contact a pond dealer and ask your questions. I will say that we run a 1000 Watt heater on our indoor 300 gallon tank. Do we need that much? probably not. But with the digital controller, it doesn't matter. I read somewhere (but don't quote me) that 1 Watt per gallon is the recommended starting point). When my 1800 tank gets set up, I plan to start with three 1,000 Watt heaters.

Your question has actually been asked and answered on MFK. Fully insulated and covered pond with a radiant heating system.

 
I had about 1500 gallons of tanks in my "fish house", directly heating and lighting about 1000 gallons of those tanks.
The power (electric and gas) was on a separate meter from my residence, so I could monitor the fish energy cost.
In Jan, Feb, and Mar, the fish house ambient air temp would drop into the low 50s'F, and my energy bill for those months, averaged about $400.00 per month, so I would imagine heating an outside pond would probably be at least quadruple, perhaps more per month.
So if it were me, I'd put one of those semi permanent green houses over the pond most of the year, even when heated.
In Wisconsin my outdoor ponds would freeze solid to the substrate, so I had to bring even cold water fish inside.

yea i like that idea. greenhouses would also protect the pond from outside predators too
 
Agree about predators.
Where I lived raccoons were a constant problem in my open ponds, until I sheared off the sides, and dug them deeper than 3 ft. Before that, I would find headless Gymnogeophagus and other carcasses on the patio, the raccoons would eat the head and discard the rest.

ill keep this greenhouse in year round with some soft of additional heater.
