My nitrite levels have been high. I keep one betta per 3 gallon tank and I have two betta. They are in a tank that has a filter and activated carbon that came with the tank. Both tanks have a higher than normal nitrite level. I have taken some action to bring the level down. But, for the future, should I get additional filtration. For instance, I have seen form mats or something in the store that goes under the gravel. Please advise.
