Review on Cobalt Aquatics 50021 Total Nitrate by Jessica Kennedy

Claims to be placed in Media Reactor but is not. It all ended up in my septic tank and aquarium, and it took me several hours to get out. Most of them are just waists. Even at very low current it still flows up the exhaust pipe and into the sump. Also, it makes the water very viscous and thick and clogs your filter socks very quickly. That's why I still have to change my filter socks twice a day.
