Δεν γράφει κάτι στη συσκευασία ή στο μπουκαλάκι. Κάπου διάβασα για 12 μήνες μετά το άνοιγμα αλλά δεν ξέρω αν ισχύει:
''A bottle size 20 ml will be more than sufficient,
A 3 day course is recommended.
Day 1 for 200 Ltrs, 50 drops.
Day 2 24
Day 3 24
Hakf dosage should not be necessary, It is safe for shrimp etc. Also totally safe for filter etc.
It only has a shelf life of 12 months once opened.
No need to run carbon etc after treatment, one of the best meds Ive ever used.
It will turn the tank water a lovely shade of light green, but this dissipates a few days after treatment.
Regards
Fred.''
