dear beginner,

Do you have EDTA or other chelate agent ? How about trace elements ?

BTW, are you using your own pmdd ?

DEAR ALEX,
I'M USING MY PMDD AND MANUTEC STICK ONLY.

Great, would you mind sharing your experience and content of PMDD.

sorry, what is PMDD?
I think EDTA is the best chelate agent

DEAR ALEX,
MY GREEN PLANTS ARE GETTING THICK, NOT VERY TALK
RED PLANTS ARE JUST OK, NOT VERY RED
SHORT PEARL ARE THICK BUT GROWING SLOWY,
EXCESS AMOUNT CAUSE SERIOUS ALGAE
NO HARM TO FISHES & SHRIMP

CONTENT,
MGSO4, K2SO4, KNO3
TRY SEARCH AT YAHOO FOR 'PMDD' WILL FIND DETIALS.
THANK YOU VERY MUCH.

Arki -- POOR MAN'S DOSING DROPS (PMDD) - actually is DIY fertilizer. Different people have different mix of PPMD, but the major chemicals are very similar to beginner’s dosing. Do you know where can we found EDTA in Hong Kong ?

beginner -- In additions to your dosing, How about the trace elements mix (contains small amount of Mn, Co, Zn, Mb, Bo,..... and chelate Iron ? In thekrib's website, this type of mix (e.g. Plantex's "CSM"
) can be bought easily in states. Are they difficult to buy in Hong Kong?

I read from the MAC website (Hong Kong), they are doing PMDD and try to replace expensive commercial mix like ECA and TMG and the result seems promising.


Thx a lot.

I STILL CAN'T FOUND THEM AR, IF YOU CAN FIND THEM, PLS. LET ME KNOW WOR. NOW I CAN ONLY USE MANUTEC STICKS AND HOPE THEY CAN PROVIDE SOME TRACE ELEMENTS LA.

從國內的網站看到EDTA 在大陸的化工店是有散買的, 而且好像不貴.
