will an unheated pond cause condensation problems in a garage? i had my 300g heated in the garage and had bigtime problems, but if this becomes a coldwater pond will i have the same problems?
The main problem is when the air temp changes radically. If the air and water temps are about the same then not much extra moisture will be taken up by the air. If the garage is badly insulated though, then you will still have problems due to the air temp fluctuations
