Indeed that could be another reason. I assumed he only dissolved K2SO4.
I believe that is one the reasons why the calculator advises 75% as a solubility limit. It's to allow some flexibility.

Yeah! There's 3g KNO3, 3g Ca(NO3)2, 1g KH2PO4.
I'll try to dissolve the K2SO4 seperately and try again. Thanks for the heads up!
Regards.

As usual the Elephant in this mix is the CaNO3. You’ve likely got near 3g of Calcium Sulphate and some Calcium Phosphate precipitate in that mix.
Calcium Phosphate/Apatite crystals are as hard as teeth (teeth are mostly Apatite), takes weeks to dissolve @30ppm CO2).
🙂
Here is < some information > provided by @X3NiTH some time ago about the reaction between calcium nitrate and sulfates.

Hmm. Okay; in that case, I'll make a seperate solution for N, P and K.
However, I don't have CO2 in my tank yet. Hopefully, I'll get it setup by next week.
That said, shall I omit the Ca(NO3)2 and replace the by CaMg(CO₃)₂ (dolomite)?

The other option which may improve the salts solubility is the decrease the pH of the solution by adding a little weak acid eg Ascorbic ach, Potassium Sorbate or critic acid, does not need to be rocket science just sprinkle a little into the solution and see if the precipitate disappears 😉
Hi all,
This is the <"solubility rules chart">.It is just like @X3NiTH says as soon as you have ions in solution that form one of the insoluble compounds, that compound will precipitate out.

No, carbonates are less soluble than nitrates.

You can see for calcium carbonate it says "insoluble", but a lot of water is "hard" (high dGH/dKH) and saturated with Ca++ and HCO3- ions which doesn't seem to make a lot of sense, this happens because calcium and magnesium carbonate are soluble in acids, and rain-water is naturally slightly acid.

Hi all,

No, they are both compounds of <"very limited solubility">, so you always need to add them directly to the tank.

Thank you Darrel. Will code accordingly.
We ( mainly Hanuman ATM) are still working hard on this and its looking GOOD and release is getting closer, but no time scale as 'real life' does kick in from time to time and all folk involved in the project are after a useful unrushed product which once release will 'Solid' and not be updated for some time (unless errors are found )
So what Commercial ferts do folks want on it to compare or clone ?????
Some are so dilute we have had to take them off eg Seachem flourish as there was so little in them there was too many zeros eg 0.000000000000000001 ppm !!!!! and when chosen it was making our effects look silly as we needed bigger cells to show the figures so the great look Hanuman has worked on was spoilt
Working on D Wongs APT range ATM - just after confirmation on a few figures as its says 1.5 ppm Nitrogen (N) for APT complete and for EST-Index it has no [Mg ppm]
On with ADA range too
So if there's any other commercial ferts you would like us to add just ask, but some are not possible as the products have no ppms or w/w% - a post of the fert and a sheetshot of the ingredients ppm or w/w% would be very helpful as finding them can be very time consuming 😉

Posted the labels with w/w% of the new ADA line on the micronutrients thread.
Many thanks as it saves searching 👍
Just the maths taking w/w% to ppms and converting K2O to K and N to NO3.
worth a post so folks can check the maths and for future reference too
( the reason the columns are so wide is its on a spread sheet with lots of other data above it which needs wider cells 😉)
So it was a typo on the webpage as product label clearly says NO3
All JBL Proscape ranged added
adding
Dennerle Plant Elixir
which has no phosphate or nitrate, but does have 0.02% Nitrogen probably urea, so once the bacteria get their hands on the N in the tank it will yield NO3 0.18ppm.
Any ideas what the ' 0.29% organic matter. To promote the growth of ornamental plants in aquariums (0,29 % Organische Substanz. Zur Wuchsförderung von Zierpflanzen in Aquarien.)' is?
They do quote the 'organic matter' for other products as well

Might be some amino acid or hormone type stuff, like ADA additives.
But vague all the same as it doesn't mention [PO4] in any of the products in the range and its probably counting the organic PO4 in the 'organic matter'
and the ppm above don't account for the organic compound the P/PO4 is attached to so [PO4 ppm] will be even(much) lower
