    Can anyone recommend a good heater of 25 watt in the UK?

    I hear the Eheim range is good, although relatively pricey. They also require calibration.

    I was looking at them on Amazon last night, they’ve got a four and a half star reviews which is definitely pretty good.

    What kind of calibration?
