Picked up Pertz fertilizer today. How to dose?

So our local LFS is going out of business and the wife and I hit it up today. Got RCS, a blue shrimp that is sized like the RCS, amano shrimp, and this Pertz fertilizer for plsntd5. At 10 bucks a jug I couldn't resist.

I'm hoping this will help with having to buy Flourish comp and potassium as often? It says there's a measuring cup but of course with this being refills we don't have it.

Anyone know how much and often to dose these 2 for a 55g and 20g? Thanks!

The refills aren't concentrated, so it'll be the same dosing as on the small bottles; the directions for K, M and N are the same:

Initial application (and after water changes): dose 3 pumps per 10g
thereafter dose 1 pump per 20g daily or 1 pump per 10g every other day.

For densely planted tanks, does 1 pump per 10g daily.

How much is a pump? Lol I don't have anything other than the jugs

Ah I don't have the origin bottles I see to refill. So either I have to buy the original sets at 15 bucks each, or does anyone have an idea on how to go about this?

Will a regular empty new of course soap dispenser work?

What no tanks ? But they seem to be the only people besides Marineworld who has the RCS. Passed through there I believe in Sept and the stock was low. Looked like they were not up to their usual standards. Now we know why.

The shortest distance between any two points is a straight line...in the opposite direction...

Tested it in my excel cap--1 pump is approx 1ml.

I've been using Pfertz macro/micro, K and root tabs the past two years. After the first few months of use, I tossed the remainder of my Flourish in the trash as not being worth using. I do think the Flourish root tabs have a slight leg up on Pfertz tabs, but it could just come down to the size of the tabs.

That said, I'm moving towards using dry ferts now. My tanks are potassium hogs so it's nice being able to customize the dosage; I'm still using my old Pfertz K bottle (being all handily labeled and all) but it's at a 2x stronger dosage per pump. Once my macros and N are gone, I'll move to dry on those as well.
