Thanks to the raffle at the last Frag Fest event at Pet Country, I am now the proud new owner of a Next Reef MR1 Nitrate Reactor system. It was filled with Seachem's de=Nitrate and I have it all hooked up and running in my sump. The pump is even in the pre-refugium area. Yes Chris I listened during the refugium lecture. I love new equipment. I will keep everybody posted on how well it works out.
