PMDD Ratio..HELP

Hi Gents,

I have seen a lot of different ratio for PMDD fertilizer. Could you please advise me most suitable ratio ?? and I am confused some dont use KH2PO4 and some use.

MgSO4 - ??g/l
K2SO4 - ??g/l
CaNO3 - ??g/l (KNO3 is banned in my country)
KH2PO4 - ??g/l

CSM+B- ??g/l

my tank (22g) is newly set up and what will be suitable dosage (ml per g?)

Please feel free to advise as I am a newbie to PMDD.

Regards,
Lynn

PMDD is an outdated method of dosing (the original recipe as described by Sears and Conlin omitted phosphates).

PPS-Pro and EI are more recent regimens that you can take a look into, depending on your needs.

Currently I am dosing PPS Pro for my 22g Tank (2 T5 Tubes, 2l DIY CO2). As I cannot get KNO3 in Singapore, I use CaNO3 instead. Since KNO3 is not used, potassium is mixing and what should i do for that?? I do dose K2SO4 as per PPS pro recipe. Do I need to dose additional ferts to get Potassium? Please help and thanks in advance .

Sorry I couldn't provide my water parameter as I do not have any kind of test kit.

Using calcium nitrate may raise the hardness of your water unnecessarily, so I would be careful (you may need to use a bit of RO or distilled water instead).

As you are losing a bit of potassium, you can always increase the amount of potassium sulfate added.

I would not worry about the excess sulfate you are dosing; by the time it reaches toxic levels, you will have other problems.
