Was cheap, so I really wasn't sure.. but man it kicked mine quick.  I just stuck in my HOB below the filter floss so it wouldn't possibly shine on any fish and turned the flow way down so the water had more time to sit in the filter.\r\n\r\nDid a massive water change (80% roughly) before I started with the light and another massive one after about 3 days.  The green still came back but not as strong after 2nd water change.  Leaving the UV on constantly this whole time.\r\n\r\nAfter two water changes and about 4-5 days of 24/7 UV it was crystal clear.  Now I turn it on for 4 hours a night when the lights are off.  Haven't had a problem since.","subreddit_name":"Aquariums","author":"msshammy"},{"body":"This is the UV light I used.
