What ways do most use to control Nitrates for SPS only tanks. Are the best way to use macro algae or media. Some people keep levels below 1ppm where as others are above 1ppm. I know everyone has their own opinion. If I want to keep my level at or below 1ppm what method would be easier. If I want to keep it around 5ppm what method. Please tell me what method you use and why. I am not wanting this to turn into a debate. Just trying to learn different ways of raising SPS's.
