I am thinking of Alum that is used to pickle stuff.

I have some old pharmacists type scales (torsion balance) that I use to measure stuff. They are very accurate, but would be a major PIA to this often.

I'll run this recipe in my autodosers...if Ghazanfar brings Calcium Nitrate and Magnesium Nitrate to the next meeting. I only use KNO3 and KH2PO4.

I have lots of extra dosing bottles if anyone wants 'em.

Kris asked that I post the latest...

Stock Solution A
H20 250ml
KNO3 15g
5Ca(NO3)2.NH4NO3.10H2O 5g

Stock Solution B
H20 250 ml
MgSO4.7H2O 3g
KH2PO4 2g
K2SO4 14g

The 5Ca.. in Stock A, is what is sold (incorrectly) as Calcium Nitrate in the US.

Dosage is easy, for a 100 G tank, use 100ml of Stock A and 100ml of B, 3 x per week. For a 75G, use 75ml etc and so forth.
Don't forget, start with half to 2/3 the amount of water, dissolve the salts and then top up with water to make the total volume of solution. E.g. if making a liter of this, you'll need to first dissolve 4x the amount of salts in say, 750ml of water. Once everything is dissolved, top up with enough water to make a 1 liter solution.

Full Excel attached for any chem nerds..
