Help wtih my fish tanks tempeture please!!!?

Question

I have a 2.5 gallon fish tank and the water is 82 to degrees how do I cool the water to the seventies? I don’t have a heater so that’s not the problem. I think what is causing this is the tanks light but when I turn it of it only goes down to 80 degrees! Please help

Answer 1

82 degrees won't kill your fish. I wouldn't worry about it if I were you.

But if you do want to cool it down, here's what I do. Freeze 1 or 2 water bottles until they're frozen solid. Then let them float in your tank until it reaches the desired temp.

Well, there are several things you can to. Directly, you can leave the lights off or switch to something that is fluorescent or uses LEDs. You can put the aquarium down lower because heat rises. I used to have an aquarium on a refrigerator, and the fish died. You can move the aquarium to a room where there is air conditioning.

There are also indirect tips that may help. They won't help the temperature, but maybe add to the health of your fish. You can get a larger tank. That allows for more oxygen and has more room for waste to settle. You can add aeration to the water. A little aeration can make the water hold more oxygen and mitigate some of the effects of hotter water on the fish's ability to take in oxygen. Something else is to select a breed of fish that can live in the temperature range of the water. You certainly do not want gold fish.

If all else fails, monitor the water constantly and do a partial change when things get dangerous. Just don't lower the temperature too fast. That can kill them.

I wouldn't try to cool the tank much more than 74 degrees as tropical fish need warmer waters. Do once weekly water changes of 10-15% with slightly cool water. Not cold as it will shock your fish and cause them to get sick and possibly die. One of the main reasons your tank is warm like that is because of the size. If you do not have an air conditioner in your home your tank is most likely staying warm because it takes a long time for water to cool down. Do not run your lights in the evening at all. Only during the day if you have to. Even better would be to not have them on at all and allow natural sunlight into the area the fish are in (not direct sunlight). In all reality though, 82 degrees is okay for a freshwater tank to be at. So I wouldn't worry too much.

Answer 4

First check the room temperature. The tank will always be at least as hot as the room it's in! Then look at the light in the tank. Try a fluorescent light, because they run cool. It takes several hours for that much water to lose its temperature, so leave it until the next morning before checking it again. You are probably just chasing numbers!

Answer 5

If you drop the temp too much you could stress or even kill your fish. You may take out a glass full of water and add a glass full of cool water from your tap and conditioner if you require it. You can also add an ice cube to the tank to help slowly lower the temp.

hope that helps
Good luck

You should be changing the water 20-25% a week and add cool water if thats the problem, if its a brand new tank (just-recently-put-in-water) you need to be changing it 20-25% daily. Hope it helps.
