Its the powders (salts) that we use to provide the nutrients that plants need. Some dry dose these powders right into the tank, some make up their own solutions using RO/DI water to get a certain standard and dose that way.

They are the same chemicals that liquid ferts have but without the water mixed already. I see it as a matter of choice. One wants to have a bottle to pour "X" amount in per gallon which is quick and easy to figure but expensive. Another may have larger/more tanks and the dry ferts are simple once one gets the dose down pat. For dry ferts, I mix the powder into a small cup of water and pour it. I don't pay for water and shipping water. I feel I have better control with the dry as it is easy to vary the amount of each.

No affiliation with site. I have never ordered from them. Just put it out their as an example of what's available.

It seems daunting but most people only use:

Macros:
KNO3
KH2PO4
K2SO4 (debatable if even needed if dosing EI lvl KNO3)

Micro:
either
CSM+B or Miller micro plex. Take your pick.

and usually
Iron Chelate

and then only if you have really low GH
once weekly GH booster after water change (magnesium and calcium)

All in all ends up being considerably cheaper than buying the bottled stuff.

Yeah but how would you know if you put too much nutrients, couldnt that have negative effects on the tank?

There are lots of different methods people use for dosing such as ei(wich is quite simple) and pps pro

You can test for
Nitrates and phosphorous with test kits
It's difficult to test for potassium, but you can't really overdose it as long as you stay within the suggested guidelines to your method of dosing

You can dose a little less than ei which would make it more pps pro or dose higher than pps pro to be more like ei. Dosing need not be so rigid but adaptable.
