I’ve used Seachem De Nitrate in my 55-gallon freshwater tank for three months. Water quality has improved significantly. The nitrate levels dropped from 80 ppm to under 10 ppm. No fish stress or odor issues. Easy to add and maintain.

Good product for reducing nitrates. Works well with my filter system. The media doesn’t smell or cause any water discoloration. Slight initial adjustment in water chemistry, but overall effective.

After switching from a sulfur-based filter, I noticed no unpleasant odors. The tank water stays cleaner longer. My fish seem more active and healthy. Highly recommend for nitrate control.
