This morning I checked the nitrates in different ways. The 1/4 to 3/4 test read .50 so that would put it at 2ppm.
When I did the 50/50 it appeared to be somewhere between 2 and 5 on the color. So if I just say 2 and times that by 2 I get 4ppm.
And the water straight out of the tank was the exact same color as the half and half. So if I misread the color of the 1/4 x 3/4 and it really read 1, than that would put that test at 4ppm also.
So I am, at this point, going with 4ppm. Which is half what I got yesterday at around this time. If this is all correct, and I have no reason to doubt the tests, then it dropped to half what it was around this same time yesterday. So it is now dropping at a better rate, or a least a rate I can see LOL
