Just after some advice on chillers. I have a 70L tank with two axolotls which I need a chiller for. I've seen so many different types and I can't figure out which would be the most appropriate. I live in central Victoria so it gets pretty hot here in summer, and my lounge room (where the tank is) gets pretty got too. I ideally need to keep the water to about 18 degrees Celsius, and usually on a hot day the water temp gets up to about 23 which is too hot. I put ice in it at the moment but it's not really a viable long-term solution.
Any advice would be greatly appreciate
