The beautiful, flowing fins of many Betta varieties are one of their most distinctive features, but they are also particularly sensitive.
Dennerle's Fin-Care-Complex contains protective colloids and care substances that help protect these delicate fins while supporting the overall well-being of the fish.
This makes Betta Water particularly suitable for maintaining the carefully controlled environment required by Betta aquariums.
Tap water may contain substances such as chlorine and heavy metals that can be harmful to aquarium inhabitants.
Dennerle Betta Water conditions fresh tap water by neutralising chlorine and binding heavy metals, helping to create water that is suitable for fish, shrimp and plants.
It also supplements the water with beneficial care substances that may be missing from untreated tap water.
Use 2–4 ml per 10 litres of water, depending on requirements.
Dose when preparing fresh tap water or during partial water changes.
Good water quality is particularly important in smaller Betta aquariums.
Dennerle recommends a weekly partial water change of approximately 25–30% for Betta aquariums. Regular water changes, together with healthy plant growth and good aquarium maintenance, help provide stable conditions for your Betta.
