Question
I was wondering if it is possible to keep an aquarium for tropical fish inside a garage in the UK? The garage is made of brick but does not have any insulation and therefore gets quite cold in the winter and quite warm in the summer.
I imagine the main difficulties with this is keeping the aquarium at the correct temperature as the range and fluctuation of temperatures would be much higher than that of those in my insulated house.
Would I need to make an extra allowances for this greater variation in temperature? Such as extra heater Wattage than usually required and potentially some form of cooling for the summer months?
Answer
It depends on the aquarium size, the fish, and how uninsulated it is, and where in the UK. I easily keep fish in a couple aquariums in a garage room addition and several more in an unheated garden shed. However both are well insulated. Your brick have a lot of thermal inertia so (with doors and windows closed) , the temperatures in the garage should not range near as much as the outside temperature. You did not mention the roof/ceiling situation, could be more important than the walls. Plastic foam panels on the back, bottom and sides will partially insulate the aquarium. Larger size will give thermal inertia to the aquarium , I would use nothing smaller than a 55 gal ( about 200 L). Some fish tolerate high an low temperatures better; I have Paradise fish that see 30C in summer and 12 C in winter. I doubt you will need to do anything about high summer temperatures; I am near Houston TX ( usually 33 C+ in summer ) and it has not been a problem . Electric heaters do well in minter; For a 55 gal 2 heaters of 150 watts would be good . And I say two because if one 300 watt fails it very likely will overheat the tank. So, it is doable , but you have decisions to make.
