mixing hot water

got_nailed, I see what your saying, it makes sense, I honestly never really thought that deep into it, you have a good point.
 
It also depends where your hot water is coming from, if you have a boiler, then its just boiling up cold water, if its in a tank, that some people have then it can get stuff in it, therefore giving you bad water to use for water changes.
 
If you need to warm the water, either using a spare submersible heater or letting the containers sit in hot water in the bathtub will bring the temp up. I don't worry much about it unless I am doing large water changes. As said before, many fish appreciate some fresh, cooler water - as long as the temp change isn't too drastic.
 
usually let it stand, but if I need warm stuff quick, I put it in the microwave to bring it to room temp. Don't know if it is good or bad though.

actually is it ok to microwave it? Aqualung, never thought to heat it that way- though I use that method to defost meat. Very effective, better than air.
 
I was not thinking about over seas where a lot of boilers are used. In the US it’s mostly hot water heaters. Some of the larger as in 200 people plus do use boilers to preheat the water and store in water heaters.


Water heaters have a Zink rod in them that will corrode before the rest of the tank. Depending on where your water comes from the Zink rod might have to be replaced ever 6 months. It is recommended to flush (open the vale on the bottom) the tank every 2 months to reduce the amount of build up. If your tank is more than 2 years old and you have never done this; there is a good chance you will end up with a leak if you try it.
 
As to the contaminants that are in you water heater... um, where do you suppose they came from? Those contaminants are in/from your tap water. So it doesn't really matter if you use the hot or not. They both have about the same amount of crud in them.

Also, it doesn't matter if you have city or well water either. In fact, unlike 50 years ago, you are better off with city water in many parts of the country. Here in Florida, over 40% of the wells tested contain choleraform bacteria that exceed 'acceptable' levels. Over 50% contain Nitrates.

The only solution is ion-exchange purification or R/O. There is no such thing as a filter that can remove some of the toxins that are in today's water. As to treating it chemically.... well, are you really removing anything? Or are you just adding another chemical to the mix that's already in there? The contaminants are still there.
