So I used Vibrant to get rid of bubble algae. It has not worked after 3months although it does seem to have slowed the growth. As other have noted it does impact corolline algae mine has died off the back glass and growth on the rocks has stopped. I stopped dosing two weeks ago but growth has not returned. It is labeled as bacteria although some say it is an algaecide. I was wondering how long it takes before the coralline growth returns should I start doing large water changes??
