I have a pretty good understanding of the EI method, how it works, CO2, lights, and all that, I really just need to know if these are ALL of the fertilizers I need to buy:

KNO3 - Potassium Nitrate - Macro

KH2PO4 - Mono Potassium Phosphate - Macro
http://www.aquariumfertilizer.com/i...rnEdit=2&Returnitemname=&ReturnShowItemStart=

Plantex CSM+B - Micro
http://www.aquariumfertilizer.com/i...rnEdit=2&Returnitemname=&ReturnShowItemStart=


It's my understanding that those are the only fertilizers required for EI dosing with dry fertilizers. Is that right?


My other question is about dosing them, can they be dropped into the tank in their dry form, or should they be mixed with water first. Are there any advantages or disadvantages to either method?

Thanks!

Some people have tap water that contains quite a bit of nitrates in it. Those people tend to use K2SO4 instead of KNO3 for their potassium, to avoid going too high in nitrates. Other than that, you have the ones that are needed. If your water is relatively soft, or your water quality report doesn't verify that you have some magnesium in the water, using GH Builder is also a good idea.

You can dose the powders by just dumping them in the tank. Don't worry about the fish appearing to try to eat them.
