How To Keep Aquarium Cool?

    Hi does anyone have any ideas how to keep aquariums cool? I currently use ice cubes in Ziploc bags enclosed by another one( just in case one gets torn open). It's not a great strategy because the ice thaws in like 10 minutes and I need something long lasting. My aquarium has 2 female swordtails and 5 female bettas and the temperature is 83F. I read somewhere that you should not keep swordtails in temperature higher than 82F. What do I do!!??:emoji_frowning2::emoji_frowning2:

    Ice packs or freeze a bowl of water. A large body of ice will last longer than many smaller individual ice cubes.

    Whats the temp in your house? Keep the lid open & if thats not good enough, have a fan softly blow the top of the water. Make sure with temps that high you have enough air circulation with your filter or a bubbler.

    I just changed out my thawed water bottle for another frozen one. I keep two each in my freezer for each tank, cheaper than buying ice packs, no chance of water leakage, quick and easy to replace. And keeping frozen water in your freezer cuts down on the electricity used by the freezer to boot lol.

    This should be a sticky, whenever it gets very warm always add another bubbler. Warm water holds less oxygen and the bubbler will make for more surface agitation which is gas exchange.

    Frozen plastic bottles work pretty well and can be returned to the freezer with trouble. Larger or don't bother. As stated a small baggy full of ice is gone quick. The fan trick does not work well in higher humidity climates. I tried cranking the fan on high and it actually raised the tank temp. It would work well if the room is air conditioned but then the tank wouldn't be hot in the first place.

    I'm worried that the label on the bottle will like poison the fishes.

    I actually froze 2 water bottle yesterday and dropped in my 55gallon community tank. Temp was 84 dropped down to about 78 ..80 but the ice cubes in a Ziploc works. Don't want to water temp to drop too much. I also put my HOB filters (Floval) I high to create more water movement....

    I posted a similar question and from what I have been told seasonal fluctuations are acceptable. If you are running at 83 and the max temp for your fish is 82 then I think you should be fine.

    Well, right now my biggest tank up and running is 10g, will use 2 liters when I get the 30g up. So green tea bottles work well for me right now.

    Since I do not run AC regularly my fishies have a normal seasonal rise in temps, I only use ice bottles on days like we have had this week, 95+ with humidity. I keep the lights off during the day, run them at night; add extra bubblers, feed sparingly. So far everyone is doing ok.

    The easiest solution: put a bottle or two in a large ziplock bag.

    If you are doing the water bottle/ice cubes route, just make sure that you treat the water with prime or other dechlorinator so if they leak they won't affect the fish. :)

    I have three tub ponds on my three seasons porch. The fish see some fairly substantial temp swings but they are gradual. After a few months of temp swings from 63F to 82F in 3-4 days, I'm pretty sure most fish are tougher than we give them credit for if we give them a chance to adapt. They are not showing any signs of distress and many are dropping fry.
