Sera Pond Crystal 5000ml

Sera Crystal e is a biological liquid that coagulates all substances that cause turbidity in the water so that they can be easily removed with a mechanical filter. If coagulated particles are on the surface of the water, remove them with a net.
How to use: Before using Sera Crystal check the carbonate hardness of the pond with sera-KHTest. If necessary, increase the carbonate hardness with Sera GH-KHplus to at least 5 dKH. Too low alkalinity will affect the stability of the pH value. Then add 50 ml of Sera Crystal per 1000 liters of pond water. To increase effectiveness, provide a strong movement on the water surface during use. In more persistent cases, repeat the procedure after 24 hours.
