Re: Sources for PMDD components

Hi Jim, I too live in a large city (Philly) and can't find these chemicals
anywhere local. Unfortunately online these chemicals require $30+ in
shipping costs alone, even for a $4 bag of KNO3. I don't know why I didn't
think of it before, I use it for everything else, I tried searching for them
on ebay and found 2lb KNO3 for $15 including shipping!! Still having
problems finding the trace mix however.

Hope that helps, happy hunting

I have been having a heck of time finding the components for PMDD even
though I live in a large city (Washington, DC) - or maybe that is the
problem.  Can someone tell me where to buy Potassium Sulfate (K2SO4),
Potassium Nitrate (KNO3) and a Chelated Trace Mineral Mix.  I have been
using Seachem products with excellent results, but I am looking to mix my
own PMDD so I can control the mix and know exactly what I am putting in.  I
have read every post I can find in the archives but the recommendation are
too general (like - your local garden center).  I have even called
hydroponics stores but they seems to all sell trade-named mixtures of
fertilizer rather than the raw stuff.   So if there is a good supply place -
online, catalog, whatever - that sell this stuff in a good water soluable
form, please share.   BTW - HEADS UP - many PMDD posts suggest that
potassium nitrate can be purchased at garden centers in the form of stump
remover.  The only brand of stump remover around he!
 re I can fine is Stump Out from Bonide,  The manufacturer says it is not
KNO3 and will kill aquarium plants and fish.  See their reply to my inquiry
below.  "Bonide Stump Out is made from a food grade trade secret product.
It is not Potassium Nitrate and if added to the fish tank, it will kill both
the plants and fish.  Sorry, it's not the product you need." Sincerely,Nancy
