Nitrite 0-25 ppm, Nitrate 0-500 ppm Two Pad Water Quality Test Strip The Nitrite Nitrate test strip is used to test for Nitrites & Nitrates in solution simultaneously. The Nitrate pad detects Nitrate in solution at 10, 25, 50, 100, 250, & 500ppm. The Nitrite pad detects Nitrite in solution at 1, 5, 10, & 25ppm.

My guess is the algae killer devastated some of the beneficial bacteria. Have you checked for ammonia? When a tank is cycling, you first get ammonia, then nitrite. Different bacteria break down the two toxins. For now, you may want to try 25 percent partial water changes every day until ammonia and nitrite are at zero. Sodium nitrite is responsible for the desirable red color (or shaded pink) of meat.

4 Allow five minutes for full color development. No. A raw comminuted product that exceeds the maximum allowable ppm of a restricted ingredient at formulation would be considered "adulterated" in accordance with 9 CFR 301.2 or 381.1 because it contains a food additive that is unsafe within the meaning of section 409 of the Federal Food, Drug, and Cosmetic Act. According to dr tims, I should not let nitrite get above 5ppm.

Continue to measure every day. My guess is that the nitrites are actually well over 5 ppm so the 50% water changes are not enough to bring it below 5 ppm. I'm starting to see Nitrates in the tank so the cycle is progressing.

As a general rule, the nitrite concentration should be less than 0.2 mg/l (ppm) in all aquariums wherever possible. The nitrate concentration should not exceed 20 mg/l (ppm) in saltwater aquariums. When nurturing hard corals, the aim is to keep the nitrate concentration below 10 mg/l (ppm).

Anything above that is toxic to fish. Nitrate should never be allowed to go over 40ppm though we like to keep it below 20ppm so that there is some space for it to rise due to--late water change, mild overfeeding, little bit of real plants turning brown (all of which could result in higher nitrate) Ammonia 1-2ppm nitrite 0ppm.

The Agency has also established an MCLG and an MCL of 1 mg/L for nitrite (measured as nitrogen) as well as the 10 mg/L MCL for total nitrate plus nitrite (measured as nitrogen). Although extreme levels of nitrate can be associated with It shows nitrite handled and clouding unrelated to being cycled. No cycling chart written agrees that this tank here isn’t cycled, but I read that in your post the only reason I test this is to see if bacteria are predictable, if there are indeed cycles not done by ninety days it means they’re not predictable, cycle charts w be useless As a general rule, the nitrite concentration should be less than 0.2 mg/l (ppm) in all aquariums wherever possible. The nitrate concentration should not exceed 20 mg/l (ppm) in saltwater aquariums. When nurturing hard corals, the aim is to keep the nitrate concentration below 10 mg/l (ppm).

Ammonia is 0. I'm doing a fish cycle. Any idea of Longer answer: ammonia and nitrite should never be allowed to go both 0 - then still test once a day for another 2 or 3 days just to make sure.
