Review: Algae nutrient supplement - This stuff is really good, not only for chaeto, but for fertilizing all macroalgae.
Review: Excellent tool for a refugium or algae reactor. - I put this on an auto doser for daily dispensing. I dose 2ml per day. Since it's addition to my reef aquarium it has certainly boosted the growth of the chaeto in my algae reactor and in turn lowered my nutrient levels.
