Today is water change day for my 55g. I drained out about 30% of the water and was all set to start refilling the tank when I noticed... "This fresh water feels cold". Quick run to the kitchen to grab the handy dandy digital instant read thermometer and what do you know.. the fresh water is actually 4 full degrees colder than the tank.
I am bringing it up to temp now, (no big deal, simply boil a gallon or so and add it back to the fresh water can).
I always try to match the temps as closely as possible when adding water to my tanks. What do you all do? Are you like me, matching to the closest 10th degree, or do you just use whatever temp you have on hand?
I'm curious to see what everyone else does.
