The most often reported result, historically, and in my tests with aluminum dosing, is closing up of soft corals, especially leather corals.

Wich levels made them close. I start to believe that the brightwell put aluminium in the tank as just shortly after it climbed in the icp and same times I realise now some of my leather Wich were thriving were closing
Will see in the next icp. What is the best way to make aluminium down?
