Hello everyone,

I decided to order 5lb of PMDD premix for my 29g and 40G. I understand a premix would not be a better solution than buying separate ones but for poor man, that's my choice.

I have made a quick calculation of how long a 5lb would last me - if my calculation is right, I am going to sell liquid PMDD. I got to do this calculation as it is not easy for me to order.

Yep, that's a lot of stuff. Just as bad as ordering 1lb KNO3, KHPO4, KSO4, CSM+B. That's how you get friends...you give a little away :)
 
Have you tried buying from Singapore?
Dr MALLICKS likely will ship etc, you will need some PO4 also.
See Aquatic Quotient web site, they are about as local as you might have there, there are some Viet sites as well.

Regards,

That give me more hope. Tom, it is really funny here that shipping cost from Singapore to my country is pretty much the same as from the US. Vietnam is easier for me by land - plants are cheap though they don't have much the varieties.

What I am trying to do is not only for my own hobby but also for the aquarium society here that I am going to establish and will work to promote such hobby currently too small to notice. I am learning from you and AC so that I can make things happen - as Beviking said "give a little away".

Many thanks everyone.
 
I wish you the best of luck Phyroath! Tom is one of (if not THE) best sources of information out there! It boggles my mind to think of how many people he must have helped over the years/decades! :thm:
 
I agree Beviking, his name is everywhere and I have read a lot about him - my favorite. I hope he continues to help people out.
