theGil Posted May 30, 2013 Share Posted May 30, 2013 Does chaeto reduce nitrates by directly consuming them? Or does it just consume the excess nutrients that would normally contribute to the nitrate levels in an aquarium? In the first case, I should be able to add chaeto and light to a tank of water with a certain nitrate level and watch the nitrate level decrease over time. In the second case, the nitrate level wouldn't change. Right? So which one is it? Thanks! Link to comment

I just knew I couldn't have been the first to ask, but search results were not helpful. Everyone was talking about "chaeto REDUCING nitrates". Gonna read now... 26 pages of fun reading on the subject here: http://www.nano-reef.com/topic/319561-refugiums-dont-export-nutrients/ 26 pages I don't suppose you have a quick answer for me?

grmoore Posted May 30, 2013 Share Posted May 30, 2013 All algae will absorb nitrates as part of their nutrient requirements. Chaetomorpha does an adequate job of it. Be sure to tumble the chaeto ball and keep it loosely packed so it can all receive lighting. Any that dies off will simply dump the absorbed nutrients back into the water column. Link to comment
Cirenus Posted June 14, 2013 Share Posted June 14, 2013 In addition to exporting nitrates it will also export phosphates for you as well which is always a huge + in my book Link to comment
