Calculating EI doses?
So for my old 40g, I just, honestly, followed the little sticker that came with the GLA ferts, which I stuck to my red-solo cup labeled ferts, to a tee. Not very glamorous but it worked. But now I'm at the point the little sticker doesn't tell me what to do. And as much as I want to say I know a lot about fertilizers I know nothing. Only thing I did differently was I only did micros twice a week vs three times a week like the sticker says. M W F was macros, Tues & Sat were micros, Thursday was Iron, due to a fear of overdosing micros. Then 50%+ water change on Sunday.
How do I go about calculating for 120g? Do I count the approx. 40 gallons of water in the sump too?
I'd appreciate any help. When it comes to fertilizers I'm not very good. I can tell what deficiencies are what in my tank with the plants I'm comfortable with, but I don't know how to form a base line on what to dose.
