New Life SpectrumRegular 600g (Naturox Series)

Most fish I have like it some don't. Only that the phosphorous content is not stated. Got a big algae out break in one tank. Not over feeding either. Discontinued use in marine, feeding to only freshwater fish now. Ingredients not listed on amazon, but when I got it I read in the ingredients list. In said list is L-Ascorbyl-2-Phosphate. Its used as a source of vitamin C but will clearly add phosphorus and is not labeled. I will probably not buy this brand again.
