JBL Ferropol

[Irn-Bru]

have a free bottle of JBL Ferropol from a friend...
I am wondering how best i can add this liquid fert into my 27 litre tank...

the instructions says to use the outside screw top for every 10 litres of aquarium water but it does not say how often i should add it...

also, i have just added a tablet (broken up) of Sera florenette A into my gravel as well... one tablet is supposedly meant for 20 litres of water...

should i still add the Ferropol? how often should i do that?

thanks

Dosing
Outside screw top: sufficient for 10 l of aquarium water
Inside screw top: sufficient for 30 l of aquarium water
Repeat doses in full amount every 1 to 2 weeks according to need

JBL Tip
JBL Ferropol may also be used as day fertilizer; first, add the full dose to the aquarium water, followed by an outside screw top for 100 litres of aquarium water added daily. The dose may need to be adjusted depending on the intensity of the vegetation. Use the JBL Iron Test Set to monitor the optimum iron content of 0,1-0,2 mg/l.
