I want to clean up my water a little.. I like to think I have good husbandry as I do 10% water changes weekly, I don't over feed or dose anything. I have a 40 breeder with 40 breeder sump/refugium that has a good amount of chaeto and flame algae on top of a mangrove plant. I still see random spots with small amounts of green hair algae, green bubble algae and brown cyano or diatom. Running a reactor should definitely help with these problems. Any advice on which either carbon/gfo or bio pellet. I've heard pretty good things about both just want more advice on the issue.
