ok so i would like to know if i am doing this right or not here as it looks really weird to me
so from following this
if i used a 500 ml pump bottle which each pump is 2ml... so i want to do a pump for each dosing which comes out to about "250" dose per 500ml bottle right? ok so to get each pump to the right amount of ferts say its 1/4 teaspoon per dosing which is 0.25 times that by 250 dose which would equal to "1/4 teaspoon" per pump, and by timing the 0.25 by 250 dose that i can get per 500ml bottle will equal to "62.5 teaspoons" of ferts for a 500ml bottle? is this right cause thats a lot of Fertz ....
so from following this

the easiest way to do a premixed fertilizer is to first decide how much liquid I want to dose at a time. That could be a syringe full, a cap full, or something like that. For example, in my case I wanted to dose 1 ounce per dose. Next, based on the size of the bottle, figure out how many of those doses are in the bottle. In my case it is a 16 oz bottle, so I have 16 doses in the full bottle. Next I calculate how many tsp of KH2PO4 I need per dose (for example). If it is 1/8 tsp, I multiply that by 16, and that is how much KH2PO4 I put in the bottle with 16 ounces of water. Now, my one ounce dose will contain the right amount of fert for one dose.

You are doing the math correctly. However, 1/4 teaspoon per 10 gallons is a very large dose. So that high dose "snowballs" when you multiply it times 250. That's one reason to use solutions for smaller tanks such as 10 gallons. Teaspoon measures are prone to error.
If you want 2ml per dose (2ml per 10 gallons) and a 500ml container the amounts are listed below.
KNO3 22 1/4 teaspoons
KH2PO4 3 1/8 teaspoons
Plantex 16 3/4 teaspoons

well i was doing the math for a 35 gallon of water tank not for the 10gallon tank
so confused on how to use the fert calculator now... is there a step by step instructions on how to use it correctly? i'm not sure if i am using it correctly or how you came up with these Teaspoon amount to mix with the water

Calculate for a 10 gallon tank using the Estimative index dosing method. Select solution instead of dry dosing. Enter 500ml for the container size and 2ml for the dose. Select the fertilizer you want to use and click calculate. This will give you a normal EI dose for a 10 gallon tank. To dose a 20 gallon use 2 doses, 30 gallons use three etc. I know it can be confusing at first but it will become quite boring after awhile.

another thing i am confused about is this here... i will explain what i did and what doesnt match up...
so i did this in my version below for a 500ml in 5 ml per dose
500ml bottle at 5ml per dose = to 100 dose possible
fertz is 1/4 TspKN03
so i times 0.25 x 100(dose per bottle) = 25teaspoons of ferts per 500ml of water
but when i used the program it says i needed 311/8 teaspoons of KNO3
am i doing something wrong here?

I don't see how measuring a liquid amount is any easier than measuring a dry powder that you scoop out and drop in. No calculations required. I have 4 tanks that I dose and 3 are 75g or bigger and hitech. Takes about 2min tops.
To each their own I guess. How the simplest things can be made difficult amazes me sometimes.

lol you can scoop out and dump in with is easy or make a mix solution and pump in what u need for 3 tanks xD
it seems to me like if i did my kno3 that 1 lb will last me about 7 months which is not bad... for doesing 3 tanks 3 times a week

so what is more accurate? the program i assume ?
also how much iron 10% should i mix into a 500 ml with CSM+B?

A 2:1 ratio seems about right. Two parts Plantex and one part DTPA. Just calculate for a total iron of 0.5ppm per dose. So that would be 0.333ppm of iron via Plantex and 0.17ppm of iron via DTPA.
So in a 500ml container 2ml per 10 gallons that's
11 1/4 teaspoons of Plantex
3 3/4 teaspoons of DTPA 10%
