EI based NPK + Microplex

The EI Method is based on the thought that excess nutrients will not harm anything in the tank.
So even if you had a low light tank and were to dose 3x per week at the full amounts, as long as you kept up with the 50% weekly water changes it would not cause any problems.



This package is designed to be used with the EI(Estimative Index) dosing method.

Package includes:

  • -2lb KNO3
  • -1/2lb KH2PO4
  • -1/2lb K2SO4
  • -1/2lb Millers Microplex
