PMDD dosing help

PMDD Premix
Bought this from AquariumFertilizer.com
1 lb contains 1 part each of Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Plantex CSM+B.

Does this stuff all come in one package?(I Think it does which would not make me happy)
If so, I have a 75g tank and was wondering how much of this stuff to dose and how often.

If it is 4 seperate parts, how much of each and how often?

I just bought the same thing - PMDD from aquariumfertilizer.com. Yes, it is one bag of powder, with stuff mixed together. It sure sounds great to me. And I was just getting ready to post a question here asking if anyone could help me figure out the dosing amt. The instructions on the bag don't make a lot of sense to me.... Hopfeully someone has exdperience with this and can help.

Hold over from folks who use to do PMDD.
You need to also get KH2PO4, but do not mix that in with any CMS+B or iron containing traces.

EI is just PMDD increased to account for todays higher intensity lighting and
and added PO4.

Some where freaked by ppm's and grams of this and that added to solutions, chemistry fear basically.

So I suggested using teaspoons and making it a bit like cooking cookies and 1/2 teaspoon of baking soda etc.

For larger tanks, dry dosing works well, basically 20+ gal, but daily dosing works well if you are going to to make that an easier habit for you.

I'd suggest using about 1.5 w/gal or T5 lights, good CO2 system and good flow in the tank, then an enriched sediment like ADA AS, then use something like EI dosing or modified versions of it.
