Is a 50 watt heater too much for a (4 gallon) Baby BiOrb?

8 July 2010 5 Comments

The BiOrb heater pack comes with a 50 watt heater. PetCo.com states that it is for aquariums 8 gallons and up, but the actual packaging says it is suitable for all BiOrbs, including the Baby, which is 4 gallons.

Is 50 watts too much for 4 gallons? Should I try to switch to a 25 watt?

The thing about 25 watt heaters is: all that I've found do not have adjustable heat settings, and they don't have very good customer reviews, either.

Please help!
Thanks.

    I have a 50 watt in a 5 gallon tank and I haven’t had any problems. The first answer was right – it hardly ever goes on but the tank still stays around 76-78 degrees.

    I will repeat my answer to an almost identical question asked here a day or so ago:

    It’s more power than you need, unless you’re keeping the aquarium in a VERY cold room. That shouldn’t be a problem, though, UNLESS the thermostat on the heater fails. The more powerful a heater is, the faster it will overheat a tank (especially a small tank) if it sticks in the "ON" setting. So keep a thermometer in the tank, and monitor the temperature closely (as you should do with any heated tank).

    With a 4-gallon tank, I would really be more concerned about how well the heater will fit in the tank. Look for a heater with a short tube, so you know it will fit and still leave room for the other stuff in the tank.

    There’s no need to worry about an over-sized heater (within reason), as it will actually prolong the life of the heater. The built in thermostat will ensure that it does not overheat the water, and you will find that the over-sized heater rarely comes on, which in turn means a longer heater life!

    The only thing to be cautious about, is to ensure that the area where the element is located is fully submerged in the water.

    Get a bigger tank. You could probably get a 10 gal. tank for less, than a smaller heater.
