Review on 🧪 Denitrate - 4 Liters / 1 Gallon by Kimberly Saunders

I will retest my nitrates just to be sure. I want to start with my 300 gallon pond filtered and full of pothos. I bought this because I was still struggling with 80ppm nitrates with my goldfish (think they're dirty). I bought these and realized they can't be in a high flow filter (it sucks, huh?). So I ended up stuffing a bunch of pantyhose into pantyhose and leaving them at the bottom of my pond while I let the water run through. I also put something in the filter with more GPH than recommended. The stones eventually turned blue. I forgot about them and checked my nitrates about a month later. 0. Unbelievable, I have huge goldfish that I feed 3 times a day.
