Little Adjustment for GHA- HUGE IMPROVEMENT

[Bkatz1]

Just something I felt was worth sharing because I was amazed at the response. In our IM 25 Lagoon I had a pretty significant GHA outbreak. I did my water changes and removed what I could manually, however the GHA was winning at an alarming rate. Before going to chemicals I adjusted my AI Prime and bam... instant reaction. I was running the blues at 60%, Green 4%, Red 4%, and White at 4%. I cut the lighting by more than half... Blues/UV/Purples I knocked back to 20%, Red and Green 0%, White 2%. For that small size tank the lights are still plenty bright for the coral, and the GHA took a brutal hit. Its is almost 100% gone. Sand bed, rocks, and coral bases are all clean. So if you are struggling with Algae it might be worth knocking the lights back before going the more invasive route. I wish I had taken a before and after shot but I really wasn't expecting that significant of results. I hope this can help someone else in the future.

Bet it had to do with reducing the amount of red. As Red wavelength is what is used in Algae reactors to get them to grow.
