On the one hand the ambient temperature, on the other hand the radiation of the sun. When the room temperature rises sharply in summer, it is important to regularly control the temperature in the aquarium. The desirable temperature is between 24 and 26 ° C. Temperatures above 30 ° C are very problematic and can cause great harm to fish and plants. On the other hand, aquariums should never be directly exposed to sunlight. The higher the temperature, the harder the oxygen vital to animals diffuse into the water. Review: Controller Repair Avoiding Cooler Replacement. - I use a JBL Cooler 300 on my 29ga tall freshwater tank which is located on the second floor. During the summer it CA, it can get overly warm. The cooler helps to minimize that. After several years, I noticed the controller plug into the cooler was getting frayed and interrupting power to the unit. Replacing the controller fixed the problem. I’m glad I didn’t need to buy a new unit.
