Poll: Which macro reduces the most Nitrates???

[fishhaven]

Maybe there is a link to this somewhere? My goal is not grow food just reduce Nitrates. Thanks for any responses.

I have chaeto and they work pretty good.

caulerpa racemosa or prolifera are usually one the fastest growers. Some macroalgae do store excessive nitrate in their tissues but I generally find that my racemosa reduces my nutrients to zero.

In my opinion caulerpa reduces the most but chaeto does just as well at reducing nitrates and does not go sexual. When caulerpa goes sexual it puts toxins in your water there for degrading it so its kind of a trade off toxins for nitrates. There are ways to aviod it going sexual but I just use chaeto.

You have to prune caulerpa regularly that's true, lighting it for 24/7 helps as well.
