About this item
  • ใ€ TREATMENT FOR FUNGUL INFECTIONSใ€‘: Use when fish, fry, or eggs show signs of fungal infections such as fluffy cotton wool-like growths. If fish have grey, velvety film over their body or have excess mucus. If fish have red open wounds, ulcers, missing scales, rotting fins, or eroded mouth tissue.
  • ใ€ TREATMENT FOR BACTERIAL INFECTIONSใ€‘: Methylene Blue can be used to treat bacterial, fungal, and some external protozoan parasitic infections.
  • ใ€ SAFE FOR EGGS AND FRYใ€‘: It is safe for use with eggs and fry. It is best used in a quarantine aquarium or treatment bath but can be added to the aquarium water, when transporting fish, or applied directly to wounds.
  • ใ€ EASY TO USE ใ€‘: Simply calculate the volume of your aquarium in litres (length x width x depth in cm/1000) or use the NT Labs online Dosage Calculator. Shake the bottle thoroughly before use and mix required dose of treatment with 1 litre of aquarium water. Add slowly to aquarium.
  • ใ€ NON-TOXIC TO SNAILS, SHRIMP AND FISH ใ€‘: The concentration of the product is non-toxic to plants, snails, shrimp and fish.
  • ใ€ CAUTION ใ€‘: Not for human consumption

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
