OK, want to start EI and so went to Planted Aquarium Fertilzer web site.

What exactly do I need to buy?

CSM=B Plantex...........................check!
KNO3 "Potassium Nitrate".............check!

What else? KH2PO4? Can't find this on the site!

Any help would be great.

If you're the type to forget dosing for a while, some K2SO4 is beneficial. Extra iron chelate isn't a bad thing to have around either.

Hows your water hardness? If there isn't enough Ca, some CaSO4 or CaCl2 is always nice.

Watch your shipping rates; there are optimum quantities to order before you go up to a higher rate.
