Is There Any Advantage To....

[aibo210]

running 2 heaters in a tank or is it overkill? I ask this as I have a juwel tank with its heater but I have a spare visitherm one from my old.

Yes. If one fails you have a back up, it will keep a tank more evenly heated, and in large tanks, there aren't big enough heaters made so you need two or more heaters.

I can see the advantages... but I NEVER have ran more than one ! I prefer the less equipment as possible in my tank !

Some people with larger tanks run 2 heaters which total the wattage required. This works well for several reasons.

• Better heat distribution
• If one stops heating the other can keep the tank close to the required temp
• If one decides not to switch on it's only putting out half the power that a single heater would have done so you have more time to save your fish.
