Heater ?

[bellebelle]

What size heater do I need for 210g tank ? 55g fuge and 30g sump.

I have heard 3-5 watts a gallon ...anybody have any input ?

Yes, 3-5 watts per gallon is correct. I go with 5 watts per gallon and use more than one heater of smaller wattages. That way if one heater burns out, you will still have the other heaters there to keep your water warm. If you only have one heater and it burns out, you could lose everything..

I'd suggest a pair of 300 or 350 watt heaters.
