So, I recently ran about a 6 week cycle of Vibrant starting with the bottle recommended dose, then after an e-mail to vibrant they recommended a 1 oz dose every other day for three weeks to start. This killed off the Bubble Algae, and green hair algae, however it did not touch the Briopsis, there was a slight die off of Brio but not what I expected. I was away on a business trip and returned to a tank full of Cyano and green hair algae and decided to discontinue use. That was Oct 1, I have good water quality, and low nitrate so I have not done any water changes except about 75 gallons from the treatment for the Cynao at the end of Oct. I have not used Vibrant since. So does it work? Yes are there unintended consequences in my opinion Yes. It seemed like it could be a solution in bad situations.
Been using for about six months, absolutely no I’ll effects, I had turf algae, tons of bubble algae, even some funky looking algae that no one could identify, all 100% gone, I went by the dosage for two weeks, small amounts of die off, then read a fellow reefer whom was dosing every four days, I tried that and that seemed to kill everything algae, even all coralline algae!! Did that for another month then decreased it, now I do the biweekly dose, if I remember!, but I still dose to keep my coralline under control on my back glass and on my sandless bottom, one thing is that all that die off creates allot of excess nutrients, nitrates will creep up and if ur carbon dosing, a whitish heavy bacteria film can easily form if ur not checking ur parameters!!
