Disclaimer: I do not have any tie whatsoever with the company and bought the product for myself. Honest review with anecdotal evidence.
My NO3 level has been pretty stable cruising between 20ppm and 30ppm in my 50g tank.
I wanted to decrease a little bit this level and chose to add 500ml of this product.
I soaked the cubes in salt water + a good dose of Microbacter7 for 24 hours as indicated on the product.
One month after introduction in my sump in a low flow area, the level is now close to 0 (5ppm last check) and I needed to increase my feeding not to drop to 0.
I believe this product works great.
