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?
