Could you please read this nitrate test

[rockhoe14er]

The color actually looks like 5ppm to me but if you go into a well-lit room and hold the test tube against the white part of the card right next to the colors, you'll get your best reading. I go into my kitchen where I have good fluorescent daylight lighting and can tell things much better. Going outside also works. Incandescent lighting which puts out a yellow hued light makes it tougher for me to read the differences.

The good news is that it doesn't matter if it's 5ppm or 10ppm or even 20ppm. All three of those levels are low enough so they do not matter. There is a big enough difference between 40ppm which is the first level that really matters. When your nitrates get to 40ppm, it's definitely another indication that it's time for your regularly scheduled PWC (partial water change)... but remember, there are many other pollutants that we cannot test for so do not rely on the nitrate test kit as to when it's time to do a PWC. Do them on a constant and regular basis... I like weekly PWC's on my tanks and the percentage of water changed is determined by the bioload in the tank. In a lightly stocked tank, a 25% PWC once a week is probably sufficient. In a more heavily stocked tank, twice a week PWC's... or if the tap water and tank water baselines are close enough, then once a week larger PWC's (33% to 50%) are OK.

For all the men out there, men have a much higher rate of color blindness than women. Here's a couple of free sites to test your color blindness. The first two are kind of quick. The third one gets really deep and takes a little while to complete.

I scored a 123. on the xrite test.... It's pretty hard. :bling:

Remember, if the instructions say to shake it for 30 seconds, shake it for a minute. Also, tap the plastic bottles on a tabletop first and then shake them up if you haven't used them in a while to make sure any settling of the chemicals is broken up and dissolved well. This is a common issue with many liquid test kits... and especially with the API Nitrate test kit.

The test looks like around 5ppm to me, though the colors may not read true from a picture.

I don't have trouble with between 10-20 ppm, but 20-40ppm are sometimes hard to determine for me.

I took the xrite test and it said:

You have perfect color vision!



Now I can tell my husband he's wrong when he argues with me about colors :rofl:

REALLY!!!!!????? **** so you got a 0? some of those colors were too close for me to tell the difference. I guess those statistics are right....

Yup, 0. I have horrible nearsightedness, but apparently I can at least see colors correctly.

37 over here.....i was getting sick and tired of doing it so i kind of gave up. Also, in addition to being sick and tired of it, i am also sick and tired.

i scored a 34. I guess that's pretty decent. Very interesting too!

Adjusted my monitor (I generally keep it very dark with low contrast, as I find it easier on the eyes. Got a 16 this time.
