Poor Man's SeaChem EQ(PMEQ)

The ratio I've been using is 3:3:1

K2SO4, CaSO4, MgSO4

This will provide a fair amount of K+ relative to Ca/Mg.
Most folks have enough Ca relative to Mg.
What will get folks into trouble in doing their calculations are that these are hydrated forms, Eg

MgSO4 . 7H2O
CaSO4 . 2H2O


You can vary and make your own, but this about close to what SeaChem has.
www.gregwatson also sells CaSO4 and PMEQ if you want it.

Thank you for this very good info! I had always hoped somebody would do a "commercial = DIY" conversion.

You have given me (though still confused about it) dosing information for my tank in another thread, but you did it using Seachem Eq. Now I can maybe figure this all out and get my dosing closer to what it should be.
