Just switched from NoPox to TM Elmi-NP. Primarily because TM is more concentrated and was burning thru NoPox. NoPox did bring my NO3 down but PO4 not so much. For PO4 I was using Rowaphos which I stopped using once I switched to TM elmi-NP. Its been a month since the switch and I will be at my max dosage which I believe is 2.5mls for a 125g tank. Does anyone dose or found themselves having to dose greater than the recommended max dosage?
