Ok, here let me break this down.... I have used both methods and I am currently using the ADA method.
EI:
When I first started planted tanks, I used this method with all the Seachem products. The plants grew great, it was high tech setup. Everything was much more controlable, such as more N with out having to worry about also adding in too much P.
ADA:
After I got a job I switched over to ADA and followed their recommended doses to the finest detail with most of their fertilizers. It's working out great. It has worked great with a low tech and high tech setup. It's macros come packaged together so you can't control them separately, but there should be no need to since it should be the amount that your plants are needing anyway. AKA the ratios are set for you with ADA. You just need to add right number pushes each day. You can also combine EI method with this ADA method because tank conditions alway vary from tank to tank. It is recommended that I push step 2 twice a day, but due to my plants need I push three instead.
So you see, one does not have to follow ADA strictly, the user ends up deciding how much to dose the tank. |
