rotala butterfly

Hi team, in an effort to confirm that my calculations are precise/ballpark, I would like to know the percentages/concentrations that the calculator is factoring for of some of the listed nutes. For example, it's apparent that when I select Fe 11%, I can confirm that it matches my Fe11% that I am...

Hi, This is regarding reminerlising my 100L tank. I select CASO4.2H2O for dose to reach target option. It shows 21g to reach 50ppm which is ok. But 7 DGH for just 50ppm of only calcium? Or is Rotala butterfly calculator also adding up 40ppm of sulphur which is shown in the results to calculate...

Guillard F/2 is a Phytoplankton Fertilizer originally used for growing marine algae. Many of us purposely culture phytoplankton to feed to Daphnia, Moina, Rotifers, Artemia, Copepods, Fish fry, etc. It would be nice to create a recipe using our common planted tank dry ferts rather than buying...

Title says it all Tom

I'd like to ask to have MgCO3 included in the calculator. Would need to show dKH and dGH as well as Mg and CO3 ppm (same info as CaCO3). Incidentally, the CaCO3 calculations do not provide the red warnings for solubility limits. EDIT: Oops: NVM the solubility limits, I forgot about the...

Be happy to walk that someone through some illustrative examples via phone or email. I think this screen says a lot: Dosing 1 ppm every 4 days shouldn't cause the concentration to increase every day. Plant uptake of .20 ppm /day should cause the concentration to decrease daily, only...

There's no (NH4)2SO4 in the calculator.

Hi, I found the source code of Nutrient Dosing Calculator v1.5.91 on Github, but it is too old, and I want to buy the newer source code. Purpose: I want to translate the source code into Vietnamese and add some of my fertilizer. Thank!

Is it possible to add dosing for MgSO4 for those of us using lab grade magnesium sulfate?

I'm trying to figure out what is the maximum amount of a dry ingredient for a given dosage when making liquid fertilizer (e.g. MgSO4 for 5 ml dose). Or conversely, If I want to use the EI daily dosing for MgSO4 in a 500 ml bottle what does the dosing size need to be to have the contents...

Minor issue that I can resolve through guess and check, but I'd imagine most that are using CaCO3 in their fertilizers are using it for the GH/KH and not so much the Calcium directly. It would be nice to have it switch to the KH as the target rather than the calcium. Or better yet, if you can...

Hi there, First of all big thank you for your great work building this community. I'm fairly new to keeping planted aquarium but I am already overwhelmed with the joy which this hobby brings to me. Not so long ago I decided to experiment with EI dosing methods which showed great effects...

Was searching something about NaNO3 and come up with simple math, but with this calculator is super cool the way to understand the target and mix up the dosing numbers, it can be added the NaNO3? Many many thanks

Hi everyone, first time posting here looking for some clarification on the ppm measurement unit. I was doing some calculations on my own trying to figure out if the calculator is actually outputting correct numbers and my own results kept disagreeing with the calculator's. I think the problem...

I'm trying to calculate AF's MacroMicro Mix to reach a target Fe, and I can't change the dosing target from NO3. Should I be able to? I can with Zorfox. (Also, AF's site says it has CSM+B, but B is not listed in any AFMMM results)

Just wanted to report that the nutrient dosing calculator is not allowing me to enter any value and is not showing any values to select from the drop-downs.

Hi, I found the source code of Nutrient Dosing Calculator v1.5.91 on Github, but it is too old, and I want to buy the newer source code. Purpose: I want to translate the source code into Vietnamese and add some of my fertilizer. Thank!

Quick explanation: I used the amount(grams) of CaSO4 for 4 gallons to compare to the rotala butterfly calculator. I did it again for MgSO4. Ca was off, and Mg was way off. I calculated the same way for KNO3 and KH2PO4, but both of those were accurate. Attached is a picture of what I did, but it...

I have three bags, one with Zinc 15% EDTA chelated one with Cu 15%EDTA chelated and one with Mn 13% EDTA chelated. I want to add some more Zinc in my tank but I don't find in the calculator anything to help me. Can anyone tell me how I can calculate theses elements if I need them????

I can't find wet's glut calculator anywhere. Am I going to have to make one myself?
