Biotope Balance pH
Say good-bye to all those phosphate related algae problems that many hobbyists suffer with these days
Balance pH 8.20 is totally phosphate free.and will not feed algae.
Balance pH 8.20 stabilises the pH at 8.20 and sets the KH to 7 degrees
To ensure ongoing pH and KH stability just add 1 teaspoon of Balance to every 10 litres of newly added water when doing water changes.
