Newbie Water Change Question

[Rossy1977]

Just about to do a first water change on my sons new/first tank (50ltr) and intending to change around 10% or so.

Really silly question I'm sure but how do I get my conditioned tap water up to the approx tank temp before adding it? I've read the water needs to be +/- 5 degrees so do I need a 2nd heater or do I leave it in the room to climatise. The only other option would be to add warm tap water but this must be a no no seeing as it'll be routed through the combi boiler!

Like I said pretty silly question to those in the know but I promise I'll only ask it once

One way if you don't need to make to much is to mix in water from a boiled kettle to your conditioned tap water insuring you added enough conditioner to treat the water from the kettle. I was advised here the water from the hot tap was not such a good plan, but I cannot remember why.

Some people say that water from the hot tap could have copper in it if its an old system. I use it though and never had a problem and my house is well over 80 years old! The human hand is a very good thermometer so just mix it until it is roughly the right temp.

I've also used water from the hot tap for years with no problems.

I always use my hand to match mixed tap water temperature to my tank. Your hand is plenty accurate enough for temperature matching.

Don't forget the dechlorinator.

I use water from the hot tap, & my hand for temperature matching.
One tip, don't add the new water too fast, slowly trickle it in.
Don't forget to turn your heater & filter off if you're removing a lot of water

Do you have a thermometer? Use it!

I fill my tank with a tube, so i have to make sure that the temperature is appropriate before adding the water.
I usually check the temperature in the tank, than pop off my thermometer, and open the water on it. I adjust it until the right temperature.
It really depends on what kind of fish you have. If you have cold water fish, then try to aim a degree or two below avarage,never above.

Good luck!
