I should expand on this. This is a mature tank 3+ years old. Neglected for about a year and started getting back into it Dec. of 18. Started doing weekly 10% water changes and added a new fudge light and growing Chaeto like crazy. I would perfer coralline algae Over this brown green red mess. I have ordered a bottle of vibrant reef. Do you think it will help and if so what reccommeded dose rate should I use. Thanks
