I have been using RowaPhos but I'm not sure if it will have a detramental effect on the Flourish fertilizers I am using...Trace, Iron, Potassium, Nitrogen. Can anyone advise?
George, thanks wasn't sure when it says 'other heavy metals' if that covered the nutrients. The tap water itself is very high in phosphate. I have been having a problem with algae and the Rowaphos seems to be having an effect. I am going to plant more heavily this weekend and hope to remove the RowaPhos soon.
