Ive read multiple threads on the Vibrant cleaner and Ive also talked to people in my local reefing group. Everyone seemed to have a good experience with it but I still didnt want to try it until it circulated more. What finally convinced me was when i talked to my LFS owner and he told me that he experimented using Vibrant in one part of his systems and another bacteria additive in the other portion. He said that the Vibrant worked much better than the other stuff and was especially good at clearing up dinoflagellates. So finally i was convinced and he gave me three doses worth of Vibrant to try out. I wanted to document my use of it so I can have actual proof of whether or not it works for me. Before the pics ill give a little info on what I can use Vibrant for. I wouldnt say my tank is especially dirty(well my macroalgae tank is) but I do have algae for on the rocks and I currently have a cyano bloom. Usually I have to clean my glass every three days and I also turkey baste my rocks to remove green algae that forms on the surface. My macroalgae tank has bubble algae on some of its rocks and has GHA on a portion of the wall. Here are some pics before the first dose. Cyano in the left corner of my 135 display. The highest flowing area mind you Glass getting dirty Green algae on rock surface GHA in 110 macroalgae tank Bubble algae Immediately after the dose many of my acros slimed up Here are pics a week after the first dose and right before the second dose.
