Hi,

I'm doing EI and I have really big biomass (I have 10 sub adults altums) in my 142g.
I'm checking NO3 twice a week-
Day after water change and day before the big weekly water change and I have always 30-40ppm NO3.
I don't add any nitrogen and I have 0ppm in the tap water.
To use only ‏K2SO4 instead KNO3? Any problem? Same quantity like I supposed to add the KNO3?
KH2PO4 I'm using normally.

Thanks!

That will work. I would just keep an eye on nitrates to make sure they stay in the 20 to 30 range.

I'm not sure it's a direct 1 to 1 substitution, I'd run it through a dosing calculator... Most of the time e.I. dosing is around 20-30ppm potassium (k) unless you notice deficiencies
