grrr chemi-clean

[untamed]

I used the Chemi-clean (I was pretty desperate). It didn't do any harm to my SPS...but it didn't solve my cyano problem either.

For me, it was improving my skimmer. While my existing skimmer seemed to be working, it clearly wasn't getting it done. Now, I'm massively overskimming according to "recommended tank sizes". The improvement was almost overnight.
