I just got csm+b and I know I now need macros but what exactly should I purchase?

Depends on your tank's needs.

Don't mean to sound flippant but have you read the EI dosing sticky?

I know it was a dumb question. I just thought someone might suggest a good macro one dose dry fert

KNO3, KH2PO4, KSO4, and GH Booster (you'll definitely use the first two and will probably pick between the last two) are all cheap. When you figure out the exact ratios you want, you can mix them accordingly and create your own mega macro.

Not a dumb question at all. But sometimes folks don't need all ferts.

And sometimes they're like me and need everything and more and can never seem to have enough. Ha.
