I've read many ways to lower nitrates, adding mangroves being one of them. How many should I get for a 90gal? Is there some rule of thumb or should I add as many as my sump will hold. Could I add some macroalgae as well, or should it be one or the other? Do they "compete" for nitrates? Anyway, just looking for some recommendations. Tank is still cycling, but just planning ahead. Thanks.
