There are just too many variables for us to tell you "yes" or "no". Your tap water parameters, plant density, stocking/feeding levels all affect that.
Gotcha TYVM for your help. I have an api nitrate test kit. Will have to invest in a po4 kit.
I know the TDS is around 150ppm Will have to check the GH and all that other good stuff.
I guess I was thinking EI type dosing + flourish.
