I do! I use the powdered version add it 10 grams a gallon, (or 2.5-3 grams a litre in my case) :smile: then use as usual hydroguard… 2 mls per gallon…

all good so far buddy!.. I love it actually, was a little expensive up front, but I cannot buy hydroguard in oz… and i have hydroguard for life… :smile:
