Anybody using this product? It's the Julian Sprung's nitrate and phosphate reducer biodegradable polymers. I just started. So it's going to take a little time to work. Two Little Fishies, INC is the company who makes this. I like it because you don't have to change every other day or so. I'm hoping it works as claims. Basiclly it promotes the growth of other bacteria that assumes the nitrate and phos. We'll see!
