Hi guys I have very high nitrates in my tank (>100 ppm) and I tried everything to lower them with no success. I stumbled upon Donovan's thread and I've been struck by the simple yet incredibly brilliant idea behind the Nitrate Destroyer, it was so sad to read he's no longer with us, he seemed a very nice and brilliant person!
So, I'm thinking about building a scaled down version of the DND on my 20g tank, I wanted to ask you some feedback about the build, specifically I have two doubts:
Since I have a small sump I wanted to use smaller tubes to reduce the total footprint. I read that the actual diameter of the tubes is less relevant than the height, would it be fine to use a smaller tube, like a 2 inch one?
Could you point out a good media combination to put in the DND with the correct order? I have Pond Matrix and Siporax in the sump so I could put them in if they are suitable, what else? I've seen many possible solution, I wouldn't want to mess up the whole thing with the wrong media!
Thank you so much for you help!
