Hi all,
Some of you are helping me on another thread about Nitrate levels, but i thought i should start a new one for this.
I have just received my new Nitrtate test kit. It measures from 0-15ppm as N
It works by putting 1ml of the test solution into a measuring cylinder, adding 20ml deionized water and then the test agents. Mix and leave to stand, then take 10ml of this solution add a tablet that gives it a colour and then compare.
Well i have been using RO water instead of deionized water.
Today i bought some deionized water from the store and i have done some tests on my water's
I sampled my tank and mixed with my RO water and got a reading of 6ppm N
I sampled my tank and mixed with Deion water and got a reading of 1ppm N
I sampled my RO water and mixed with Deion water and got a reading of 0ppm N
How does this work, it looks like i get a false reading with RO water even though my RO water contains no NO3
