i want to check in with you guys and can confirm. vibrant kills osteo dinos. i used uv and peroxide and even changed out my entire substrate. 3 days a week with dark blue lights. still....it persisted. 1 dose of vibrant rocked it all out. it DID irritate all my millies or anything with polyps out. and that initial dose made them pale out like they had no nutrients in the system. no losses. so +1 from me. vibrant will be one of the few additives that filled a gap in my arsenal.
