Therefore, our data suggest that for mice housed in IVC, which have the potential for 24-h exposure to ammonia for days or weeks at a time, intracage ammonia levels should remain below 25 ppm.” (reference: Vogelweid C.M. et al. 2011. Effects of a 28-day cage-change interval on OSHA has set an 8-hour exposure limit of 25 ppm and a short-term (15-minute) exposure limit of 35 ppm for ammonia in the workplace.

Ok, I’ve had my 55 gal fish tank for 5+ years.

Now for the last couple of months the ammonia has been staying at 8.0 ppm. I have done 10% 20% 50% water change and it's staying at 8.0 ppm. I have used Betta bowl plus, Ammo lock, Prime. Last night I did a 95% water change and ammonia went down to 2.0 ppm and 15 hours later it Ammonia gas weighs 0.000771 gram per cubic centimeter or 0.771 kilogram per cubic meter, i.e.

If you already have fish, and are having an ammonia issue, it is best to get the ammonia levels down to below 4.0. 4.0 and higher is just as toxic to TSS as it is to fish. While 2.0 -3.5 PPM ammonia may harm some of the TSS bacteria, it should still have some effect. • At levels greater than 5,000 ppm, ammonia causes chemical bronchitis, fluid accumulation in the lungs, chemical burns of the skin and is potentially fatal.

Uneaten food and decaying organic matter also add ammonia to the water. Ammonia is the number one killer of tropical fish. Using API Ammonia Test Kit is help to prevent fish loss.

I have checked the package. ammonia level was 32 ppm for only 7 d or 10 ppm or less for 28 d. Therefore, our data suggest that for mice housed in IVC, which have the potential for 24-h exposure to ammonia for days or weeks at a time, intracage ammonia levels should remain below 25 ppm.” (reference: Vogelweid C.M. et al. 2011. Effects of a 28-day cage-change interval on Even when the API test reads zero for ammonia and nitrite, and really it should even when you are cycling with fish, there is still some ammonia and nitrite in the tank, enough to grow the bacteria, even if it slows down a cycle a bit. Our testing kits are not all that sensitive. #6.
