outstanding work gents :clap: bravo

i've got my own backyard calculator which i've been using for a couple of years but that will be gladly archived for this work of geek art

The remineralizing wizards seem to be off by a factor of 100.

For example, I have set the water change to be 10L and set the calculator to clone Tetra pH/KH Plus (1dKH)

the results recommend me to doze 0.25g Potassium Carbonate into 10L of water to get 1dKH. Rotala Butterfly recommends that I add ~25g (24.62g actually) to 10L to get 1dKH. Screenshot attached

Hi all,

No, it is back to the <"powers of 10">. I'm frequently <"lost in them">.

Try the Rotala Butterfly calculator again, but put in "dry dosing" and "0.246g" of K2CO3. It is just more straightforward that way.

Your extra 100 (10^2) comes from the 200 mL "container size" and the 2 mL "dose size" added to the 10 litre tank .

cheers Darrel

The 'potential' new version has a new sheet for Remineralising is maybe a little clearer with a choice of making a Solution or Dry salts 'when' a solution is selected and not possible due to limits with solubilities it only shows as dry dose.
for eg CaCO3 is very insoluble at neutral pH

So, I've taken a good run at this calculator lark but I can't get a sensible output for what I'm trying to make it do so perhaps I can be steered right.
I dose Tropica specialised and I'm noticing pin holing and yellowed out leaves which tells me po4 and iron and maybe k are a bit on the lean side, this would make sense as the water from the tap is right 'ard so also less available.

I want to bring my dosing up to say "lean Ei" and create a ml per litre, per day, number that I can then multiply to the tank volume.
Eg. my tanks are 18 and 38 so lets call it 20 and 40 with the filter volume. 40 X x = y Ml per day of Tropica specialised.

water from the tap is right '

So is mine, and it recently came to my attention that the [Fe] and [Cu] in the tap water are within EU limits but vary over the year by 100 fold, plus excess in one element can result in symptoms of deficiency of another.
Checking your water companies water report may highlight any big fluctuations. Folk who use hard water have more issues and I think these fluctuations in trace elements may be contributing (if not the root cause) of the problems people have with hard water, the higher dGH and dKH may have nothing to do with the issues

you can use any of the preset regimes eg

or just set your own ppm targets

if you have entered you tank volume and dosing regime ( and water report details as well) the calculator will do the rest and report any issues on solubility of your fert solution

I think I must just be daft, I can't get it to put what I'm after, do I have to put in a water report to get it, because I don't have a water report I can easily lay my hands on.

The idea of the water report in the CoreSettings sheet is so that one can design a fertilizer in accordance to the tap water you are using in your tank. This basically allows you to customize your fertilizer to your own particular water report. Personally I think the Water Report function of the calculator should only be used if you know for a fact that a specific element is constant throughout the year, else don't use it. Simply create your fertilizer according to your preferred PPM targets in the TargetCalculator sheet.

Now, above you mentioned "Lean EI". What exactly is that? The calculator offers 4 types of DIY EI or other commercial fertilizers to choose from.

If those don't suit, then it's all good. You don't need to do a clone. Simply input the PPM you want by setting your own preferred targets as mentionned above by @Zeus.

If I didn't answer your question, please let me know.

I have detected a small inconsistency with "NilocG Thrive+ All-in-One" in the calculator. If you wish to clone that fert and want to follow the max guidelines of NilocG (Dose is 1 pump (2ml) per 10g, 1-3x per week Each) then in the calculator you need to "x dose by: 3" to have the proper ppm for a 3 times dosing per week. This minor issue was introduced in the latest version 1.07. All versions before that are correct. In reality this is not really an error but the calculator was designed in a way that we took the maximum advertised dosing of each commercial fertilizer in order to bring values closer to EI. This said, to allow users some flexibility the option "x-dose by:" is there in case one wants to reduce or increase the dosing easily.

I will correct this in the next version but wanted to give a heads up for anyone wanting to clone that fert.

I started to use this calculator and it’s really great, however I found it difficult in case you want to mix dry nutrients with some branded products.

basically I’m not able to put a data for GH booster. If you take a look on the original Tom Barr’s EI instruction you can add Seachem Equilibrium toghether with dry salts.

"1/4 teaspoon of KNO3 2-3x a week (every other day)
1/16th teaspoon of KH2PO4 2-3x a week (every other day)
Traces added on off days as the macro nutrients, so 3-5x a week, 5mls each time.
SeaChem Equilibrium or GH BOOSTER 1 teaspoon after water change"

Do you mean you can't target GH? If that's what you meant then you are right. The calculator at this point of time is not able to target GH directly, only Ca and Mg ppms separately. Maybe, I say maybe, this will come in the future as @Zeus. has been putting some hard work on it but no warranties on when and if it will be released with that feature. Any changes made to the calculator, even the smallest ones, usually requires from my side considerable amount of work due to quadruple checking/code re-writting/formatting/logical flow etc etc as I am very cautious about how the calculators look, its usability and user flow.
