OK first thing first, I don't want to bash this manufacturer, in fact I think this food is great. Like I said I have been using this fish food for over a year now and my fish are healthy. With that said and done, the brand of this fish food is called New Life Spectrum Marine Fish Formula
www.nlpublish.com. I talked to some friends about this as well and this is what they basically said. The fish need some of the
trace elements in their diets. Also the
copper would never build to levels high enough to disturb anything. Also fish need some
phosphates in their diets.
Is this true?
