In my mind, ADA fertilizers are essentially EI dosing.

For a high light tank for example, they recommend daily dosing of Step 1, 2, or 3, + Brighty K, + Brighty Lights or Shade. So this is daily dosing of traces, potassium, nitrogen, and phosphorous. Pretty much exactly what EI is. (Not to mention they also recommend weekly dosing of ECA.)

Agree with Salt.
Right now I'm quite poor from dosing as recommended!

so you mean salt that EI and the ADA ferts are just the same, no need to buy the ADA ferts?

Plants have simple needs, NPK, Carbon, traces and light. If you can get cheap agricultural grade chemicals to provide any or all of the fertilizers, the plants will do just as well with them as with more expensive stuff in a bottle. Even if you are doing substrate fertilizing, and ADA aquasoil means you are, you can still use water column fertilizing to provide the plants needs. So, why not use the money you spend on expensive ADA fertilizers for something else the plants or fish need?

I have been dosing per EI and everything is going great! I think what Salt meant is that the idea is the same, to overdose and "reset" with water changes.
