another newb dry fert to liquid question

[cjThomas]

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% [email protected] 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!!!

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.

geektom... gorgeous german blue in your pic.... i had a pair in the last set up and plan for the same in this one.... I don't suppose you have a line a where i could look to find them when im ready, do you? ;-) i noticed that liveaquaria.com has them, but.......

edit: upon further review.... IS that a german blue ram?? the color is a bit different....

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.

Rahul,

excellent. thank you very much for the insight. rotalabutterfly it is.
