Yeah Jay is right I did stop using it as I think the instructions causes you to dose it way to much. I was getting dust algae on my glass like crazy. I did however cut it back to once a week and so far its working fine. I did notice a huge difference though while I was using it.
Good water chemistry
good lighting and good maintanance is the key to a great reef tank in my opinion and as in others too.
I agree Tom, there is no magic potion, however what works for one person might and or will NOT work for another.
I tried this product, prodibio and ya know what I was getting much better results and response from my corals color wise and health by just doing the old fashion water changes.
People see my tank and always ask "What do you do?" I clearly tell them anymore, Nothing! I just do water changes and feed the fish. I let what happen-happen from there.
