• This becomes extremely toxic to fish when high levels of nitrite persist in the aquarium for more than a week.
• Newly established aquariums are prone to higher longer lasting levels of nitrite.
• Densely populated aquariums with marginal filtration will exhibit persistent nitrite levels, improved filtration, proper maintenance and regular testing for nitrite is recommended.
• Test weekly to ensure nitrite is detected.
