Vacuum up the detritus with a gravel vacuum hose during wc's.
Copy that? Im vacuuming all detritus on weekly basis, all this hard scape is planed for an easy maintenance. One huge log and 2 rocks needs to be moved and job done. But I must admit that no matter how well I clean there are always some “bits” left.Vacuum up the detritus with a gravel vacuum hose during wc's.
Yeah that second bottle is a bugger! You really gotta shake it hard. I'd suggest it's probably off a bit from the use of the more liquid parts in previous "tests" so I'd take the color you are getting with a grain of salt so to say. May not be as red as it shows but better safe then sorry or get a new test solution.

It's probably dirty test tubes. They need to be cleaned with distilled water between use. Some say even three times to make sure they are clean and you get an accurate reading.View attachment 1415885
Hey look at that guys, i’ve tested my tap water?
Is that possible?? Could it be caused by old api master kit? My have expire date 10.20 so its close..
I never wash it with distilled water so Im hoping its that.I hope it is whatJexnell mentioned, a simple case of unwashed vials, because if that truly is your nitrate reading from your tap that is an absolute bummer.
Do a retest with thoroughly cleaned vials and if it's the same i'd get online and check your municipal water report, it should shed more light on the situation.
Like I said you were not shaking bottle 2 properly so the solution is most likely off now as the solids were not getting mixed in before. Now your test solution is faulty. Could dirty test tubes be a contributing factor....yeah sure. Ill tell you a little secret, I wash mine in standard tap water and after they dry before the next test I rinse them with the tank water I'm testing very well. My tests are really close to when I go to the lfs with a sample. I used to buy distilled water to clean the test tubes but I realized it's not worth the extra effort most of the time. What's it going to be off by maybe 5ppm? You can't tell that on the API color card so instead of 10 you have 15 no color change not even on the scale. If it was really 35 and now it's 40 well you can't tell it's 35 anyway, what's the harm do a waterchange it's not going to hurt the fish if you do an extra water change. Just get a new test kit and rinse your test tubes out really well with tank water before you do the test on that tank. And for the love of God shake the crap out of #2!View attachment 1415885
