False low readings happen all the time with the API nitrate kit. BANG THE PLASTIC bottles, not the GLASS tubes.

Not the test tubes or vials, i.e. not the things in your picture. The bottles that the chemicals come in, there's two of them for the nitrate test and we're talking about the second one of those, bottle number 2, they're plastic.![]()

Shake and bang a few times. The banging is very important, it releases the precipitate which can settle and solidify in the bottom of the bottle.![]()

@ BigbruiserAL, You were 100% right.... just did the test the way you said to do it... see the results below...
First pic is from tank water..

this second pic is tap water...

both seem to be around 30-40ppm even the tap water which i left over night....

Try do doing the nirate test but this time hit both platic bottles of a hard surface a few times and then shake as per instructions...10 second shakes is not enough they require the full amount to be any where near accurate
tis very hard to see the colour in a photo but if your tap water is near the 40ppm i would call your water local company there is a legal limit in the uk cant remember but is not far off 40ppm

Also could it be that i should replce my juwel nitrate removal sponge? I havnt replace any of the sponges, checked on a website said that the nitrate sponge should be replaced every two months?...
