So I have a 135 gallon fish only and the more fish I add of course the more waste and even the skimmer I have being rated for tanks up to 250 gallons isn't enough to bring the nitrates I will have in the future to close to 5-10ppm. So does anyone have any advice or suggestions on either chaeto reactor or denitrator? Which one works better? I'm choosing not to do an algae scrubber just because I want this to be a little more clean and not space consuming. I had an algae and worked well but having a fish only and the chances of having a fish to eat any algae that grows in the main display won't be enough to consume nitrates. I will be adding more biological media since this tank is about a month and a half old. But what do you guys think?
