Nitrite in a freshwater shrimp tank only equals one thing - problem. Shrimp are almost intolerant of any nitrite and if your levels do suddenly rise you can tell by observing them - shrimp tend to sit still and stop feeding when unhappy - some may die within 24 hours. When shrimp stop feeding you know they're in trouble and this is their 'alarm bell' ringing. To make matters worse, large water changes are not an option as shrimp cannot tolerate that either so it would appear there are not many choices left! Until now...
Genchem Biozyme is a brilliant product that reduces ammonia and nitrite instantly without the need of any water change. But like most Genchem products they have a two fold effect. The other added benefit is Biozyme will improve the metebolic digestive system of your shrimp and baby shrimp can also consume it!
It doesn't get better than that :)
