Serenity pH6 Block 20g
Place entire block in aquarium, one block treats 120L.

Replace block with a new one when fully dissolved. It is not recommended to increase pH by more then 0.5 in a 24 hour period.
For new aquarium or large water changes use pH down powder to set correct pH (as this is instant) then use these blocks to maintain desired pH.
