You can transform your BiOrb 30 or 60 into a tropical tank with the addition of a Heater Pack, this includes everything you need to create the right environment for fish suited to warmer water- a heater, a unique stand suitable for the spherical shape of the BiOrb and a thermometer.
You can upgrade the heater to the Intelligent Heater +Powerpod, which not only heats the water, but powers the pump and light too. At a safe, low voltage of 12 volts, this ensures not only convenience but safety too. Included in the heating collection is a useful submersible thermometer. This can be attached to the inside of the BiOrb and presents a constant, fuss free reading.
