Excel in lieu of HCl

[csmith]

(or you can use a mix of Fe DTPA + CMS+B, at 1:4 ratio and mix 1 table spoon to 1 liter of DI water, add HCL or Excel to prevent fungus etc)

In what ratio is Excel used as a substitute for HCl? I've seen Excel has a limited shelf life, so how much is needed to be used in 1 L of liquid ferts, or is it the same amount?

According to Seachem, Excel's shelf life is 4 to 10 yrs.

I add about 25 mls per liter.

Hello,

Do we also need to add HCL or Excel for the macros solutions?

 

[csmith]

I do for both macros and micros.

Hi,

Thank you. I'll add some Metricide14 to my macros also.
