I just wanted to give an update on this stuff.
I am using it as the sole media in both of my Emperor 400s on my 125, and all I have to say is WOW! My water is more polished than ever
. It works much better than even using the cartidges that come with the Emperors. I have had problems with gloomy water with tons of tiny particles in the past and this stuff has made such a difference. I am stoked to have found something that works so well but also costs so little.
