cld or hot water after a water change?!

Thanks and I guess I forgot to mention that I also unplug my heaters this time of year so my tank temps are around seventy five to seventy eight degrees.Congrats on getting your water changes done.
Very nice that your "cold" faucet water is very close to tank temp (makes things easier). My cold water faucet temp is probably around 72-75°F...so I still need to use hot water (but certainly a lot less than in the Winter)
I try to do the same thing (reuse as much of the "old" water as possible). This time of year is great...since I use my "old" fish water to water my potted plants, gardens, and other outdoor plants. Plus the nitrogen in the waste water certainly helps as well!
I keep my home thermostats set at 80-82°F this time of year...so I should probably unplug my heaters as well. Strangely (I keep my tanks at 78-80°F) I see the tank heaters "tick" on every now & then. I know that the thermostats in tank heaters are not super accurate...but still odd when house temp is set (at or above) tank temps.

Almost all of my tanks are on a drip system that drains into our garden on the side of our house. Plants love it and I use cold water only going in the tanks. Gravity fed drains......
But either way its perfectly fine to use hot water to equalize tank temps.

Aww come on...that just makes tank water changes way too easy! Ha ha!
I'm betting Florida cold water faucet temps are pretty warm this time of year.
thanks guys yea ive been dealing with fishtanks for about 5 - 6 years now and that question just popped in my head now lol just didnt know if maybe the hot water or the cold water would kill different types of bacteria that they need or dont need.......THANKS AGAIN
It depends on how you add the water to your tanks.
- If the "5 gal bucket method"...then you can totally control the exact temp of the water in each bucket.
- If the "Python" or "hose method" (going directly from the faucet to the tank)...then it depends how you do it.
With the hose/Python method...you can do it two ways:
- add just cold water...then add hot water to end up with the correct tank temp. I don't like this method (depending on how cold or hot) faucet temps are (since you can potentially really stress the fish)...depending on how large of a water change that is being done.
- before adding water to the tank via the hose...blend the cold & hot water coming from the faucet (correct tank temp) BEFORE adding to the tank. This way nothing is stressed from a temp perspective.
match the temp ereing on the side of colder is better then hotter... more o2 in the water itself.. but also when it rains ect and your fish in the wild get hit w/ a temp shift w/ new water... its generally colder not hotter... hence why to instigate breeding a lot of people do a big water change and bam they breed... extreames in either direction should be obviously avoided but imo it doesn't really matter TOO much unless you notice your fish prefer one way or the other... I've always gone to the colder side but if I kept fish like Discus ect that like Hot water I might ere towards that...
Makes me wonder if some species could be triggered to spawn by doing warm water changes vs the cold ones you generally hear about.

I've always heard that it's the warming of water that helps to induce spawning (when water in the wild warms up when going from Winter to Spring). So in an aquarium environment...slightly warming the tank temp in combination with a water change can help induce spawning.
Of course with fish like Convicts (which seem to breed under all conditions)...there may not be a "straight-up" answer!
