I don't know if anyone knows this product or not. There little pill looking things that you place under the plants in the gravel. There are several types for different plants.

I have notice after puting them in there is a quite a spike in nitrite, 0.8mg/l for a few days and then back to normal <0.3.

I don't know if this is normal and wonder if I am harming the fish?
