Water Quality Report

[scottjames1uk]

I have just got my water quality report from my local water company but a little confused with all the numbers. Basically i read a while ago that if you let tap water stand in a container for 24 hours or so then it is ok to put straight into your tank without treatment but sometimes it depends on what the original water quality is like. Can anyone shed any light on this for me.

This used to be the case because chlorine dissipates usually within 24 hours of water being put into a bucket.

This is no longer the case because chloramine takes 1 week to dissipate and is already used in many areas and starting to be used in the rest.

Also dechlorinator "removes" heavy metals, which can be harmful to fish.
