Morning all, I’ve set up a 10 gallon quarantine tank in my garage (external from house). The garage isn't heated and as we are in Scotland it’s pretty cold in there just now. I’m aiming for 79 degrees of heat to match display tank, although the heater is set to this it hasn’t got up to target temperature and has been running for 4 days now. Can I put another heater heater in the tank to help? Do you think it’s the ambient temperature causing the issue ie the heater is struggling to cope? Thanks
