Review on 🐠 Efficient EA Premium Nitrate Reducer Filter Pad 18x10 for Aquariums and Ponds - Cut to Fit, Top-Grade Quality by Barbara Gonzalez

Working! Lowered my nitrates in hours! In my photo: 1- 0 nitrates 2- my high nitrates before the filter 3- nitrates after 8 hours with the filter The color is yellow with no nitrates. The darker the liquid, the more nitrates. As you can see (#3) the color is lighter than #2! The reason for my purchase is to try to stabilize nitrate levels. Lol My tank is spinning and I add a general purpose live plant fertilizer that contains nitrates. I need this filter to keep the nitrates at a safe level until things stabilize.
