So makes it a little tricky. I was only looking at Seachems Equilibrium the other day/week. they used all sulphates
But then the solubility for CaSO4 isnt great but doable IMO.
so for 100l tank a clone of Seachems Equilibrium

the result above for CaSO4 show it for the dry dose weekly which accounts for the SSL with CaSO4

So the SSL for CaSO4 is close to its limit !!! maybe a fine tune needed

Thanks Zeus, that’s awesome. So the Calcium Sulphate is going to be the sticking point.
The James Planted Tank recipe is (ignoring the Kh for now):
0.4g Calcium Chloride Dihydrate
2.0g Calcium Sulphate Dihydrate
2.0g Magnesium Sulphate Heptahydrate
25 litres Water
I’m planning on changing 75 lites per day on the new tank, so I assume I’ll need 3x that, i.e.:
1.2g Calcium Chloride Dihydrate
6.0g Calcium Sulphate Dihydrate
6.0g Magnesium Sulphate Heptahydrate
75 litres Water
So from your spreadsheet, I’d need 3 litres of water to dissolve those 6.0g of Calcium Sulphate - am I reading that correctly? That’s a bit of a blow to morale - I was hoping to get it all done in a couple of hundred ml lol
It’s still doable, but means I probably need to up the size of the salt mixture storage tank to 60 litres+ to get a few weeks worth in there.
Is there another alternative to the Calcium Sulphate? I assume Sodium Chloride can’t just be straight substituted as it’ll add too much Chloride?
PS - that spreadsheet is awesome - you really need to get it integrated on a webpage, you could add some Google advertising then and make a few quid off your efforts!
