Help! How do I cool the water down in my tank?

Here you go:



The first 3 sentences have nothing to do with the situation and as such do not help. The last sentence is simply bad advice.

Fish are already stressed from being at a higher temp than normal. Your advice to do a daily 50% wc with temp lower than the regular temperature a few days in a row would increase the yoyoing of the unusualy higher daily temp for already stressed fish. It is bad advice for that situation.

Guess we will disagree then. It is solid and practical advice.

The OP was stressing because his tank was at an abnormally high temp. There was nothing off-topic about the posts which were made to offer help to the OP.

After Hurricane Ike my power was off for 2 weeks and the temp in my house, and in the tanks, was in the mid 90s. I fed very little during that period as I had no filtration going, just some battery-powered aerators. I did daily large-scale water changes on every tank. The tap temp was 10 degrees cooler than the tank temps and the partials were around 75%. I had several delicate species at that time; 12 tanks going. My 125 gal housed a school of wild Tefe Green discus. During the whole endeavor, I lost one green fire tetra which may not have been attributable to the power outage.

In the wild, rivers and lakes are seldom a homogenous temperature. Fish move into and out of different temps at will. Some benthic species move between a temp difference daily of twenty to thirty degrees.

http://aquatek-california.com/cooling-fan-series/#4-fan works wonders!! Oh & for the record, during summer power failures here in the northeast, I've often done multiple cooler W/C's on my other tanks with no ill effects. The Discus tank I have no worries but cooling the others down a bit (5-10 degrees) with W/C's is perfectly fine. "T"

wow, adding cooler water to a tank is not so bad.. remember cooler water will be tempered by the already higher water temps in the main tank. doing a water change of 10-20 % using cooler water will have only a small effect on the temp in the main tank which in many cases has heaters in them to bring the temp back to the norm.

that said.... I think it's important to think about the problem.. how much higher/lower is the water temp from the species desirable water temp.
remember that many species are already subject to differing water temps in nature.

large lakes have thermoclines in them and rivers, stream etc are subject to changes in temp due to weather conditions, snow melt etc.

adding cooler water my not be as stressful as many would think.

my altums and discus seem to do quite well with it ;)
 
Evanleigh, I hope your ac got fixed and that your fish are fine. I hope you did not mess with the water temp because it would have been a cause of stress to the fish in the situation you described.

Also, remember to double check your information, especially online.

Keep us posted.

also, lol
