I have noticed that this activated carbon effectively keeps the water clear, removes odors, cuts down phosphates, and prevents chemical warfare between corals.
The product cleans up water well and lasts for a month or two before needing to be changed out.
98% found it easy to dose and apply, while 2% had difficulties with the measuring instructions.
