Sorry Pitbull for not riplied before, but I didn't saw the thread. No I don't have a high nitrate problem, because I realy take good care of my tank and have lots of filtration. I do a 5 gal water change everyday to maintain my quality. I think I'm the right guy to give advise on your task, but yet again some people think I'm crazy. So if you take it from me I will say that they will be alright. Once again don't try this at home.
