    i don't know why i cant seem to get my head around this... im certain at this point that im over thinking this..

    Ive read and read and re-read all that i can find... and in the end, i *think* the answer has been staring at me the whole time.... so just to verify...

    if I am using Nutri-Calc V1.9.3.... and i input my tank size as 70 gallons (and have the EI Dosing box checked), leave the NKP targets (they are weekly, yes?) as the defaults (20, 30, 3).... can i just use the rounded Grams value to create my liquid solution?

    basically then.... i will use a 500ml bottle for macros.... and a 500ml bottle for CSM+B....

    in the macro bottle, i will load 500ml of RO and:
    12.55gr of KNO3,
    5.67gr of K2SO4
    3.55gr of KH2PO4

    in the micro bottle i will load 500ml of RO and
    2.20gr of CSM+B

    this will give me 3 doses of macro and 3 doses of micro, correct (roughly 166ml each)?? and next week, i'll make another batch, lol...

    i realize that i am under utilizing the solution size... and that this equation, can and is, cut up a thousand ways by countless calculators... i just need to make sure that this basic premise is sound before i tear my hair out...

    70 gal tank... started up on 7/25/17... 2 kessil 360we suns at 50% max@ 8hours, CO2 at 30-40ppm currently (no livestock yet), gh/kh 4-5 degrees.

    i have been using Aquavitro for macro/micro and am making the conversion to dry ferts... but geesh, i am just struggling with this for some reason!! lol... help!!!

    Chris.

    Are you simply looking to dose EI levels of each Macros and micros?

    I put your above numbers into Rotala Butterfly.

    70gal tank
    500ml bottle
    166ml dose

    KNO3 = 9.7603 grams
    K2SO4 = 13.3396 grams
    KH2PO4 = 1.4867 grams

    Your micro numbers are basically the same.
    CSM+B = 2.4445 grams

    These numbers were based off Rotala Butterfly's EI calculation.

    Not to sure if that helps or not.

    thank you for the reply....

    yes... just looking for a starting point on macros and micros; im finally getting my tank back up after a 2 year hiatus and decided to go the dry fert route over the bottled junk ive been overpaying for in the past.

    your insight helps a tonne; and... im not crazy then... i keep running numbers between the nutri-calc calculator the rotalabutterfly calculator and Zorfox's calculator and i keep coming to seemingly (from my current ignorant POV) wildly different conclusions with regard to how much of what to use...

    i know that EI is simply a general rule and starting point, etc.... but the differences seem greater than arbitrary or estimative... its been driving me nuts, lol... i keep thinking im using one or all of the calculators incorrectly.

    i had hit the same numbers as you suggested using the Rotala site.... so that makes me feel a bit better....

    the rotala site doesn't seem to take into account that im dosing potassium from three sources... but in reality, i guess its not really that much greater than the 30ppm target (37 and change).... i suppose thats where experience and fine tuning come in...

    Thank you slipfinger for taking the time to help out the ignorant... it is VERY much appreciated...

    I am right there with you on being confused from getting Potassium from 3 different sources- it seemed like so much when I added all 3 together! But if the target is 30, then I am actually under that, so I guess not.

    Actually, it is a Bolivian Ram, and it wasn't mine- just a picture from google because I hope to keep a School of them in my next tank, which will be a 150g

    Just stick to one calculator and you should be fine. I use rotalabutterfly only. I have confirmed their results by manual calculation.
