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.
I am trying to pair Ghazanfar Ghori's Macro mix with whats available at GLA. I can match up the ingredients for all of Solution B, but I am not sure about 5Ca(NO3)2.NH4NO3.10H2O in Solution A. The calcium nitrate is there Ca(NO3) and NH4NO3 the internet tells me is ammonium nitrate, and H20 is water. Is this somehow a sub-mix of Solution A? Can someone help interpret this line?
The mixes at GLA seem awfully small. How long do they last (approx as you are using different gram sizes of each).

You can usually find them on Amazon or eBay cheaper, but I don't think often in larger quantities.
Wait... well actually THIS is a 5lb bag for $15. So same price for 5x as much. A guy on Planted Tank has been making his own micro mix, and he sources from Amazone.
For those interested, I edited Ghazanfar Ghori's macro mix excel, mainly to determine how much to purchase and how long the batches would last based on tank size and dosing. Hopefully, I didn't make any errors. Should be attached.
