High water temps due to A/C in house going out

[Ram419]

Hi all, should I be worried and if so what exactly can/should I do to remediate if so? My tanks are hitting about 80 degrees farenhite right now and it's just morning. The temp inside is 80 degrees and currently outside 85. I hoping to get someone out to repair the A/C today but not sure how long it will take. It should be getting to around 95 degrees outside during the day today.

Hello Ram. A large fan pointed at the tank should keep things a bit cooler. Also, make your water change water a little cooler. You could float small covered plastic container filled with ice in the tank as well until the air conditioning problem is resolved.

Hi, thanks! Yeah, started running a large fan in room but didn't help much. I have 7 tanks but most are smaller, the larger ones being 20 gallon and 55 gallons. The ice helped a lot, so I'll have to keep on top of changing it out today it seems.

Just keep the house closed up and the fish will be fine.

Don't feed the fish when it's really hot.

Turn off any electrical appliances not needed in the room with the fish tank. Leave the filter running and if possible increase aeration/ surface turbulence.

Raise the light unit up above the tank about 12 inches so it doesn't warm the water, or just turn the light off for the day. the fish and plants will be fine for 24 hours without light.

We have similar temperatures in Perth and my fish were fine when it was 100F outside and the tank temp was 86-90F. Lots of aeration helps keep the oxygen levels up. Then let the fish rest.

Thanks, yes I do have a couple lights that run a bit hot so turned them off. The other NICREW LEDs I have seem to not be so hot but they are also not the grow lights version so that may be why.

Would having the water fall back into the tank to break the surface help with cooling it down? I'm thinking about the granny's who would pass their tea from cup to saucer and back again to cool it down enough to drink

Agree with Colin. Temporary high temperatures are tolerable by most fish. In the 1990's my fish room had no air conditioning and the tanks got to 90F during heat waves, cooling back down a bit at night. I lost no fish. Later in my house I got the fish room temp down to 80F during heat waves, no lower, and for 18 years this has been no problem.

Do not use ice, cold water, etc. Leave the water alone, except for surface disturbance from the filter and a fan blowing across the surface if you like. But changes due to ice and cold water changes are more harm than good. Temperature shifts seriously impact the physiology and metabolism of fish.

Temps stayed around 79 to 81 on most tanks all day. The ones with better fan access and higher water surface aggitation from bubblers stayed lower temp.
The larger tank is at 83 but hasn't gone higher. Fish all seem good no signs of distress. The A/C is fixed, bad capcitor. Still waiting on temps to go down inside house though, 100 showing on outside thermometer atm.
