Comments: Works, but using on my 37 gallon reef tank...unfortunetly we here in the good old USA don't use the same dry weight measurement system...It said that the 125 gram container will work on a 125 gallon tank..ok, so 1 gram per gallon....uhhh, how much is a gram??? I guessed and the green hair algae is literally coming off everything...I hope I didn't over dose the tank..no one has died yet and it's been a week.... Yes, I would recommend this product to my friends.
