For me, it’s barely enough to just open the cover. On another aquarium, I’ve had to put a fan on it. This 25l aquarium went from 27°C down to 25 with the fan.

    I think that I’d go the diy route: Computer water cooler loop cooling the aquarium water: Either with these peltier cooling things. That’s just an idea, it’s not tested. Maybe sb else has done that somewhere.

      Good luck and do share your solution once you have it :)

      That’s just a heat exchanger with the surrounding air.

      • If you need to go under air temp, anything else than a cooling system (think fridge) won’t be enough.
      • if you need to drop close to air temp, afaik the best cooler for a water tank is surface evaporation. There might be a diy way trying to increase evaporation (water circulation on a ramp with fans blowing on it or such).
