Re PMDD ingredients

Since there is interest in group chemical order here is more info.
Unless someone knows more cost effective places, I will order thru Canadian
source for CSM (trace minerals) since it has the least Copper in it.  I
think is available only in 5 LB units for about $30.  I will check that
prior to order.
Other chemicals, I will get from "litemanu.com" hydroponics company in
Oregon.
Prices:
Potassium Nitrate $2.35/lb  Could also choose stump remover which is cheaper
but I am leery of cotaminant risk.
Potassium Sulfate $5/lb   Chemists out there can validate/correct me but I
think that K2SO4 is heavier per TBS than KNO4 so will need to order bit more
to come out even.
I will do some checking for a "clean" stump remover brand and check with
litemanu.com to see if we can get better price on stuff in bigger units.

I would order amounts based  on Conlin and Sears formula in hopes of "coming
out somewhat even" on individual chemicals.
1 TBS CSM  (Boric acid is needed to add Boron to CSM. It takes very little)
2 TBS K2SO4
1 TBS MgSO4 (Epsom salts) cheap at drug store
1 TBS KNO3  This is one that is likely to vary the most in amount used
I would order the first three things and Boric acid if I don't already have
it and everybody can get their own MgSO4
If anyone is interested in Monopotassium phosphate, litemanu.com carries it
and could be ordered to or since I have some on hand and a little goes a
LONG way, I can split or trade what I have.

I run about 20-25 planted tanks at any one time and  use a lot of nutrients
so I am good for about a cup of trace minerals and  proportionate amounts of
rest of the stuff.

Interested people can let me know how much they want of each item or amount
of trace mineral and take rest in proportion. Bear in mind that I am not a
chemist or pharmacist and although generally of good nature, am not likely
to be willing to split this by the tablespoon for people.
I would be willing, club rules permitting and if legal, to measure out
single recipie amounts that could be offered to members thru the club at
small profit which would go to club.
Board of Directors/Officers---is this something that could be done thru the
club if wanted?
