Default Nitrate testing

Hello,

I have an API master test kit for freshwaterautolinker.com autolinking image that I use for testing nitrates.
It is kinda hard to tell sometimes how much nitrate you have unless you do it twice, once before a water change and another one after.

Are there other test kit that is better than the API? I have seen a nutrafin test kit. Has anybody used this? How does it compare to API?

I was just watching CSI and one of them has a device that is checking fo nitrates. It would have been awesome to have one of those.

I would say that you need to do a balancing act between accuracy, precision, and ease of use when it comes to test kits. For the most accurate, I've heard Salifert test kits are the best. API is the easiest to use of the liquid titration kits, in my opinion. Precision when it comes to nitrates, however, is next to impossible. This is because instead of measuring for 1-8 ppm, as with nitrite and ammonia, nitrate tests range from 0-200 ppm, so precision with color charts is very hard to achieve.

I wouldn't worry about being overly accurate and precise with your nitrate testing, especially if you have live plants. There is a wide range of nitrates that fish can tolerate, and the higher the nitrates, the more your plants will love you.

I have a Nutrifin Master Test Kit and an API Ammonia and PH Test Kits. I like the API MUCH better. The way the color is on the Nutrifin Kit when I hold the test tube in front of it to try to get a reading the color on the color chart then does not seem right. But, when I hold the test tube in front of the corresponding API color chart it is MUCH easier to pick a close color.

Default Re: Nitrate testing

I was just wondering if the API is the "best" nitrate test kit out there. I am just having a hard time telling the difference in the color specially the 10/20 and the 40/80. I guess my main issue is in the 40/80 range. If it is 10 or 20, I should be alright. If it is 40, I might still be OK. If it is 80, then my fish might get sick. So now when I think it is in the 40/80 range I do a water change right away then I have to test for nitrates again to make sure that it has gone down to below 40. Add all the shaking that you have to do and the leaks on the test tube, its just not as "fun" as the nitrite and ammonia test.

I tend to think the nitrate test is more fun than the rest, solely for the shaking part.

It's all a matter of personal preference if you ask me. I swear by most of API's products.

Hi,

It's not much the shaking but more on the leaking part. I have to really hold the cap tight, it makes me nervous about breaking the tube in my hands.

I've been shaking and testing for two years or more and the only two tubes I've broken were when they slipped out of my hands and went sailing across the room. Just keep pressure on the ends of the tube, don't squeeze the entire thing.
