Because my well water has a nitrate concentration of 20 ppm I plumbed a nitrate filter into the cold water faucet of one of my sinks near the tanks. I use a python to deliver nitrate-free water, almost. The cold water temperature is about 64 degrees F. So I add a little unfiltered hot water to the nitrate-free water to deliver water to the tanks with a temp of 77 degrees F. This of course adds some nitrate. My tank heaters are set to 77 degrees.

I did an experiment today adding only nitrate-free cold water to a 29 gallon and 60 gallon tank. This was a 25% water change for each tank. The tank temperature after the exchange fell from 77 to 73 degrees. In the 60 gallon tank I have a. thomasi, a. caudalis and p. pulcher. In the 29 gallon tank I have several species of livebearers. Do you think a 4 degree drop in temperature over 45 minute water delivery period puts the fish in danger?
 
Just a dumb suggestion...

If you pass your cold water in a tube coiled in a bucket of hot water before putting it in the tank.

After a couple coil length and quantity of hot water tests, you can have permanent solution that will warm your water just enough before entering the tank.

If you use a python kit... It's really easy to ®patent.

Such a tool is readily available at any brew supply store at a reasonable cost.
 
Once again the worlds of fish keeping and alcohol come together.


So, now that the door has been kicked wide open, what about adding a half of shot of whiskey to the tank instead of using a coiled python in a bucket of warm water. Wouldn't that keep the fish warm too?...Just thinking out loud

It can lead to a lot of breeding, but the broodcare is just awful.

I have been told by fishkeepers I respect (but have no studies to back me up) that a 4 degree drop is the max. Now, did they say 4 celsius or fahrenheit? I've never tested it to find out, except when I wanted to trigger Cory spawning.

If the fish are newly arrived, you'll know if Ich is present.
 
I get it, me too where the economy or quality is a factor. The chiller at the brew store replaced one I made a long time ago. Better quality and faster cooling, (important in brew making from scratch).

Oh yeah, but at some point... It's clear manufactured has a lot more thinking behind it than a guy alone and if the quality is right... I prefer to buy a refrigerator instead of making it myself...

I knew water had to be tempered in winemaking, but I didn't knew that kind of device was available.

That's a device that could prevent a lots of peoples being forced to have a heater in their water holding tanks.
 
initially my thermometer dropped that much, at the heater on the same side I added water... the rest of the tank, likely equaled out a lot higher, and in doing it several times, before allowing my holding tank to get to room temp, I had no issues with any of my fish...
 
It might be a little why some users never comes back after 3 posts...

To do a perfect shadow water change... Hotter water will rise and want to stay on top.

With water slightly warmer than what is in the tank, start pulling out water out one bottom corner and let slip the new on the top.

This way is mixes less with the old and gives a better % of really replaced water.
