Serenity pH6 Block 20g
Place entire block in aquarium, one block treats 120L.
The block will dissolve slowly and release vitamins and minerals designed to keep the water at pH6. It is important to keep water at the right pH for Tetra, Discus and Angelfish.
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.
All fish benefit from a 25% fortnightly water change, remember to add a water conditioner to detoxify tap water.
