Keeping My Tank Cool

Hi all So in August I moved to Western Australia which is essentially a desert. Up until a few weeks ago I was running a heater in my tank to try to maintain temperature stability but now during the day outside temperatures get to thirty-eight and at night it's never below twenty degrees. Yesterday it got to forty degrees outside and my tank temperature hit thirty. I've been told to expect it to get close to fifty degrees when we actually get into summer and I'm getting very concerned about my fish. When I had gold fish I just used to leave big blocks of ice in the tank as a way of cooling the tank down but I'm not sure if this would be okay for my tropical tank? Is there a better way to cool down the water? Unfortunately we don't have an air conditioner in that room, and my partner isn't happy with me running a fan all day. Thanks

Thanks Sue, I really like the coke bottle idea. I can't believe that didn't occur to me lol

Hi Aquamaid Yes, I've started freezing a water bottle and putting it in the tank before lunch. In New Zealand I worried a lot about winter power cuts as well but here I've actually taken my heater out of the tank lol

I love the idea of a DIY chiller I'm actually going to give that a go. Thank you

Haha my fiance loves the sun. He'll be out there all day reading while I'm huddled right next to the air conditioner!
