How many different answers you figure on collecting?...I suppose we could even go with 3:2:1 ratios depending on how much hardness was desired. This EI isn't rocket science and can be tweaked for specific tanks as needed...
With only a few notable exceptions, Lake Tanganyika being the primary, most natural bodies carry about a three-to-one ratio of calcium to magnesium. Potassium is a macro, but not to the extent of calcium in concentration, so it's relegated to the same level as the magnesium.Their inputs carry a lot of weight compared to my WAGs. What's your numerical input on this?
aquariumfertilizer.com - Barrs GH Booster is composed of 1 part magnesium sulfate, 3 parts potassium sulfate and 3 parts calcium sulfate.

So 1/2 of GH booster is K2SO4 anyway.

This is Tom Barr's Poor Man's GH Builder/Booster. Barr's GH Booster contains: Potassium Sulfate, Calcium Sulfate, Magnesium Sulfate.
So GH booster formulas by volume dry mix...
No. I've asked barr before. The guy who makes barr booster makes it 3:3:1 Ca:K:Mg by volume.So GH booster formulas by volume dry mix...
No unchelated Fe or Mn as my crypts supply all the rust colors desired.
Seachem = 3:1:1
PMDD ver = 3:3:1 ?
Tom's EI ver = 2:1:1 ?
Is this correct?
Edit: thanx jaafaman for the input. Looks like there are some variations to the formulas, but they would all work depending on the tank plants, light & CO2 levels.
Tom Barr's own words on his site: 10-02-2009No. I've asked barr before. The guy who makes barr booster makes it 3:3:1 Ca:K:Mg by volume.
Seachem's is the same. No idea about pmdd never heard of a gh booster fo pmdd.

Volume vs weight?I think units are being mixed...
