Using the 50 ml bottle:
Shake the bottle well before use. Attach the enclosed tube to the syringe and measure the desired amount of ZOOTONIC with the syringe. The air that gets into the tube and syringe while pulling the syringe, does not affect the dosage. The bottom edge of the plunger always displays the correct dosing amount even if the desired quantity of ZOOTONIC, due to the air drawn in, is only in the tube and not in the syringe chamber. The air drawn in serves to empty the tube during dosing.
Using the 200 ml bottle:
Shake the bottle well before use. Turn the pump head counterclockwise until it pops out. Pressing the pump head once is equivalent to 1 ml.
Begin with a daily dose of 0.1 ml per 100 l (26 US-gal) of aquarium system volume and increase the dose when necessary.
