Update and let me know how it works out. I just put some in myself, used my containers on my emperor 400 to place it in. I wasn't sure whether it or Kents worked better either. Also just changed over to using RO/DI water. Bought two 5 gallon containers and bought the water for .50 a gallon from the LFS. Gonna start using it for top offs and partial changes. Hopefully the mixture of the two will help get the red algae under control.
