CO2 levels ~30ppm (@ peak) decimated the Staghorn Algae that I had for a while after moving a tank, but I still have Thread & Hair Alagae.

I'm curious if anything in Excel acts as an algaecide in a way that pressurized CO2 does not. I currently use pressurized CO2. Nutrients are all balanced, lighting period is 10 hrs/day (~3 watts/gallon), etc. Can't figure out what could be causing it & would rather spend a little $ on Excel if it would get rif of the algae.
