Blue Exit is a safe and effective solution for eliminating cyanobacteria (blue-green algae) in freshwater aquariums. These unsightly and potentially harmful algae often appear due to low nitrate levels, excess fertilisation, or an imbalance in the bacterial environment. Blue Exit treats these conditions without the use of antibiotics or copper-based compounds, making it safe for all aquarium inhabitants.

Unlike harsh chemical treatments, Blue Exit is harmless to fish, shrimps, molluscs, and plants, and is suitable for routine or prolonged use. In cases of heavy infestation, the treatment can be extended or dosed at a higher level for improved results. This makes Blue Exit a practical option for ongoing algae control without disrupting the aquarium ecosystem.

Key Features:

• Effectively removes blue-green algae (cyanobacteria)
• Free from copper and antibiotics
• Safe for fish, shrimps, molluscs, and live plants
• Easy to use as part of regular aquarium maintenance
• Can be extended or doubled in dosage for severe infestations

Blue Exit offers a balanced and safe method to restore the health and clarity of your aquarium by targeting the root causes of cyanobacteria growth, helping to maintain a stable aquatic environment over time.

Specifications:

• Use: Cyanobacteria (blue-green algae) remover
• Safe for: Fish, shrimp, molluscs, and plants
• Chemical content: Copper-free, antibiotic-free
