Aloha! I used Vibrant in my RSM130 for a round or two of treatment per bottle directions.
Some background. I had picked up the tank and inhabitants from Criagslist and it had tons of neglect. Hair algae, bubble algae, aptasia, red slime, and worst of all ended up being derbesia ... I got rid of the slime, hair, and aptasia but couldn't dent the bubbles. Eventually tried Vibrant and it took a little while, but definitely had a positive impact reducing the bubble algae. However, I did lose my Cheato pretty quickly. For the coraline, I wouldn't say it killed it off, but i think it slowed it down. After those 2 doses and about 6 months of patience. Closely monitoring my feedings, h2o changes, testing, etc. i got nailed with the derbesia... What finally cleared that up was a round of flucanozole (Reef Flux) treatment - which also finished off the bubble algae.
Right now the tank has been pretty clean and all coral and fish are super happy going on 8 months. Even started Acro frag

Sorry for the long winded reply but thought some context may help. This battle has been ongoing since i got the tank 3 years ago and is now finally stabilizing and clear. Did vibrant help - yes. Did it make drastic improvement overnight - nope. Did it kill off some stuff - cheato i think yes, but coralline ... meh maybe not so much. More likely i didn't have as much as i thought hidden among the other issues..
Many things out there can help us, we just need to temper our expectations maybe, and for sure be patient and take our time learning what is interacting in our systems.
Recent pic of the tank attached. Hope this helped.
