In my 180 gallons, I am fighting Nitrate for the last year after a system crash. I am doing big water change but the nitrate always stay high (between 25 ppm and 50 ppm). If it's true, some people has reported nice result after using the NP Bio-Pellets from SWC in their system. Their nitrate went down after 2-4 months. Therefore, for less than 250$, I have started a reactor with 1 liter of these pellets about 2 weeks ago hoping that the nitrate in my system will go down. I will let you know the result within a month.
You can see my little 180g tank before my system crash on my personal website at

Note: It's just a plain page with a video of my tank on it. (it's not a commercial website).
You are a very nice guy to open your house to all of us. It will be very nice to meet you. So, next summer when I will go in the Toronto area, I will pass by to say hello. And maybe you will also teach me some tricks on your nineball pool table :lolspin: I am so bad :sad2:
