"I love this. First, on the bottle it says its safe for all fish types, so I use this for all my little aquariums...including my amphibians! But the best part since its made for SMALLER tanks the directions say "7 drops per gallon". This is sooo helpful.
I hate it when the other bottles say teaspoon per pint (etc). Its like first, I don't have a teaspoon handy and its just a small betta bowl, I don't want to do math just to convert into pints! This is stuff is so awesome! Yeah for drops! For example if you have half a gallon, I would add 4 drops. 1 gallon, 7 drops, 1 and half gallons I would use about 10-11 drops.
Small and sleek this is easy to travel with too which is great for dorm rooms like mine."
