Serenity Aquatics pH6 Block

Calcium Sulphate, Magnesium Sulphate, Sodium Chloride, Thiamine HCl. (Vitamin B1), Humic Acid

Place entire block in aquarium, one block treats up to 120 litres. 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 Tetras, Discus and Angelfish. Replace block with a new one when fully dissolved. It is not recommended to increase pH by more than 0.5 in a 24 hour period.

NOTE For new aquariums 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. We recommend Serenity Aquatics Complete Water Treatment.

To calculate approximate aquarium capacity: Length x Width x Water level height (in cm) and divide by 1000 for Litres.
