Prove by who? Could you post the link to the scientific study?

It definitely did not work for me. I ran only Blue+ for over a week and it had zero effect.

Unless by blue you mean Actinic, which has little value to any tank, and which most people are no longer using as better lights have replaced them.

Sorry, but this did not work for me. Cyano is a bitch.



I say Manually remove daily. Chemi clean is a bandaid you may have to redose again.

Try Chemipure Elite.

It is great. Give it a read. It takes about 6 weeks but the product lasts for about 6 months in your tank before replacing.
