Chiclid addict Posted May 24, 2021 Share Posted May 24, 2021 I’m trying to figure out what this reads it looks between 20-40 but it also looks like 160ppm witch makes no scene because I changed the water on Friday Link to comment Share on other sites More sharing options...
lefty o Posted May 24, 2021 Share Posted May 24, 2021 id say 80ish. would be easier if you had the test tube over something white vs sitting on top of oak. 3 Link to comment Share on other sites More sharing options...

BigRedd Posted May 24, 2021 Share Posted May 24, 2021 (edited) Dang what did you do to get the Nitrates that high? Never seen the red before, looks about 80 to me. I usually use this: and hold the color up to the screen Edited May 24, 2021 by BigRedd 1 Link to comment Share on other sites More sharing options...

Verify with some test strips, but personally I do not press it against the paper. Not enough light gets through and it will always look darker. 1 Link to comment Share on other sites More sharing options...

I use test strips to test for hardness, and nitrates. Too much work to do it for other things that a test strip can easily handle. Could be maybe you didn't quite administer the test correctly? That's what I'm hoping for. Beneficial bacteria should still colonize in the filter, what type of filter do you have?

MDoc Posted May 24, 2021 Share Posted May 24, 2021 The 40 and 80 are indistinguishable on the API test. If there is ANY difference in the color on the chart, I can't differentiate. Link to comment Share on other sites More sharing options...
sudofish Posted May 24, 2021 Share Posted May 24, 2021 40+ on Nitrates are all the same to me on the api card. I think that's why everybody says keep nitrates below 40. It's because once it reads 40 it could just as easily be 160, so better to just change that water out lol. I use these images that I found linked on a youtube video. I'm probably not allowed to post the link but if you google "How to read the API Master Test Kit colours" you should be able to find it. Link to comment Share on other sites More sharing options...
Tanked Posted May 24, 2021 Share Posted May 24, 2021 I'm with the 80ish group here. When testing, reading against a solid bright white background is beneficial when the test results are questionable. For what it is worth, I test under daylight lighting, holding the vial directly against the color chart. When read thru the vial, the color bar closest to disappearing is the correct reading. 1 Link to comment Share on other sites More sharing options...

It’s an aqueon hob filter meant for a 30g but the tank is a 10g and there is extra media in the filter when I get a chance I will re test Edited May 24, 2021 by Angelfishlover 1 Link to comment Share on other sites More sharing options...

Did you shake the liquid you add 2nd vigorously for 30 seconds before adding the 2nd drops for the Nitrate test? I believe if you don't do that, the results won't be accurate. You also need to shake it for a minute after you add the 2nd dose to ensure accurate results (hence why I use test-strips, too much shaking for me) Also, just out of curiosity, what are your ammonia and Nitrite levels at? I'd imagine if your ammonia and Nitrites aren't spiked, it could be user-test error. Edited May 24, 2021 by BigRedd Link to comment Share on other sites More sharing options...
Fish Folk Posted May 24, 2021 Share Posted May 24, 2021 I'd say . . . consider doing a water change 😜 1 1 Link to comment Share on other sites More sharing options...
Grassypeak Posted May 25, 2021 Share Posted May 25, 2021 This is a huge problem with the API tests. I have better than average color vision and I cannot compare a vile of red liquid to their color chart and come up with a reasonable guess as to what the nitrates are. How are the coop test strips with respect to readability? Cheers, Chris Link to comment Share on other sites More sharing options...

Cheers, Chris I've found that reading the chart on a computer and putting the vial up against a white background works well as the light coming from the monitor passes through the vial and allows for easy reading. 2 Link to comment Share on other sites More sharing options...

I'd imagine if your ammonia and Nitrites aren't spiked, it could be user-test error. For what it's worth, I once had 0 ammonia and 0 nitrite, with nitrates over 100. I guess the bacteria were doing a great job of chewing through the ammonia and nitrite, but the resulting nitrate had no way of leaving the tank. (Life made it impossible to do water changes, and I had no plants at all.) 1 Link to comment Share on other sites More sharing options...
Grassypeak Posted May 25, 2021 Share Posted May 25, 2021 I still think that there should be a better way to register the results than red VS. ever so slightly more red. These reds are both in the range where we really want to know the exact answer. I wonder if you can use a Hanna Checker with fresh water. Then again if the test strips are easy to read and reasonably accurate that would probably be even better. I'd really like to know what my EasyGreen dosing is doing to my nitrates and API is not helping me. I can't imagine that most people don't have the same problem. When we do the color vision test in my class I almost always beat all of my students. I can see the difference between the reds on the chart but comparing the liquid color to the chart color is really just a shot in the dark. The computer screen idea is a good one but the colors of the chart are very close and the color of the liquid has a different quality than the color block on the chart. They never match in my mind.
