Water temperature advise

Postby Sumit K Sen » Tue Sep 15, 2015 3:41 pm

Hi Folks,
I have this 19 liter nano tank. Due to high prevailing temperatures I added a cooling fan recently. The fan reduces the tank temp by 3 degrees on an average in the location that the tank is placed. I currently do 20% daily water change and usually keep the 5 liter can in the same general location as the tank. But the jerrycan does not benefit from the airflow, and short of setting up a fan to cool that water, what I end up with is new water which is 3 degrees higher in temperature to replace water that I have discarded from the tank. I don't know if a net one degree swing in tank temperature in a few minutes is a matter of concern. I hope it does not, because I have used colder water to reduce high tank temps in the past without deaths in much larger tanks, of course. But I'd certainly benefit from the views of the experienced, especially because in such a small tank every problem gets magnified by huge degrees.
Thanks for your time and help.
Cheers!

If you wanna do a huge wc, the safest way is to add water as slowly as possible. I put a chair on the aquarium desk, put a bucket on it with water filled. Then I take out desired amount of water from my tank and i replace that amount of water from bucket with a tube having a cotton plug. It takes 6-7 hours for a 90% water change in case of my 7.5 gal tank with zero casualty. Though I dont do such large amount of wc and won't recommend it.

Thanks. That is very valuable advise. I was thinking of, maybe, doing two 10% changes instead of 20% at one go. Your suggestion works better. I just hope that my wife does not throw the bucket at me because it will surely be unsightly :D

Place ur Jar in the room where the fan (Ceiling) runs most of the time. The temperature of the water will remain nearly same as ur tank's.

Thanks Vikram. I change water early in the morning and unfortunately, even with the fan on, the mini cooling fan on the tank appears much more efficient in dissipating heat. The temperature difference exists, and it feels odd when you push in warmer water in a cooler tank. It is possible that a open bucket of water will work better, but when one is at my age, the house is no longer at my disposal to do as I wish. The tank sits in a study area and TV viewing room, and an open bucket sitting there is a recipe for disaster :D The jerrycan I somehow manage to store out of sight.
But really happy that so many members chip in to help. I gather that most members are of the view that such water temperature conflicts should be avoided. I'll find out a way to minimize the impact based on the suggestions received.
Cheers!

this may sound noobish but I really dont care abt water temp while doing WC. round the year, every week all 11 tanks starting from 3.1L to 150L. 50-70% depending on stock. Including fr Discus. This is my way and with so much wc i really cant worry abt the temp. never faced any deaths due to this, however, tap water contains high co2 levels and air stone is must when doing large wc or else fishes are gonna come to the surface and get very stressed .

Thanks. I suppose it is a matter of degrees then.
Depends on how you get your tap water. Mine sits in a huge underground tank and very large overhead tank before entering taps. The water that I get on tap today is a week old on average. Fish almost dance in joy when this water is added because there is always a lot of beneficial oxygenators in the underground tank till the annual cleaning is done :D

Thanks Dipankar. I kind of like dimming the lights for half hour before sunset and blacking out all light after sundown. The tank is not lit at night and is covered from room light. Any particular reason you prefer a night water change or is it a matter of convenience. I would love to know.

What are the inhabitants Sumitda? If possible, I prefer two 10% wc than a 20%, there are lot more parameters to worry about than temp..by lowering amount of introduced water you can dilute the changes in parameters.
