yea it does. I had my powerhead on and it eventually looks like it mixed it. But I didnt really like how it worked. So thats why i am going to try to exchange it or get my money back. If I cant i make do with it. Plus everyone says it puts in too much excess nutrients and to top it off it doesnt fee my acans and other LPS.
I just bought this based on my LFS reccomendation. I have not even opened it because the last thing I need is more nutrients. I have algae to deal with already.
I used this stuff for a while and it just fuelled my cyano, As above mushrooms will live happily all day long on floating detrius and excess food waste from the fish.
Suffice to say i binned the bottle as it was imo a complete waste of money
