my vote is for sulfur media (for just nitrates), it won't do you much good on its own unlike the marine pure, etc. It will need to be in a reactor of sorts, You can build your own sulfur denitrator easily for about 100 bucks including the sulfur media. There are alot of good designs out there, personally I plumbed mine into my my return pump. In waste water treatment these are called trickle filters. Some places do make them specifically for aquariums, you can buy one online if you didnt wanna build one.

I used to carbon dose, but it just never seemed to cut it and I ended up with crazy cyno.. Sulfur denitrator crushes it, the water that comes out the effluent is 0ppm. But be warned sulfur reactors will throw off your alkalinity so it will no longer be consumed in equal parts of calcium and alk rather your alk demands will get higher.
