The NT Labs FMG Mix is a highly effective, professional-grade treatment. Specifically, it combats a wide range of common external parasites and fungal infections in Koi and pond fish. Indeed, this powerful formula combines two trusted, fast-acting agents (Malachite Green and Formalin) to create a synergistic effect. Consequently, the mix offers superior results against pathogens that cause disease. Keeping NT Labs FMG Mix on hand, therefore, ensures quick treatment for common illnesses.

Targeted Pathogens for NT Labs FMG Mix

Furthermore, this broad-spectrum anti-parasitic treatment is specifically formulated to eliminate or control:

  • White Spot (Ichthyophthirius multifiliis): The gold standard for treating the free-swimming stage of this parasite.
  • Skin and Gill Flukes (Gyrodactylus and Dactylogyrus): Effectively disrupt the life cycle of these common external worms.
  • Fungus (Saprolegnia): Acts quickly to treat visible fungal outbreaks on fish skin.
  • Velvet (Oodinium).

Usage, Dosage, and Safety Instructions

The potency of the NT Labs FMG Mix requires careful adherence to instructions to ensure fish safety and treatment efficacy.

Dosage:

Use 10ml of FMG Mix per 364 litres (80 gallons) of pond water.

  • Above all, you must always calculate your pond volume accurately. Never guess.

Application:

  1. Preparation: Switch off UV-C units, protein skimmers, and carbon filtration. Crucially, you must maintain continuous, vigorous aeration throughout the entire treatment period. This is mandatory because Formalin significantly reduces dissolved oxygen (DO) levels.
  2. Mixing: Measure the required dose. Next, dilute this amount in a bucket of clean pond water.
  3. Treatment: Subsequently, slowly pour the diluted mixture evenly around the pond surface.
  4. Repeat: If needed, you can repeat the dose after 7 days, but only after a minimum 25% water change.

Essential Safety Warnings:

  • Aeration: You MUST increase dissolved oxygen. In light of this, use an air pump and air stone to vigorously aerate the water.
  • Temperature: Do not use below 10°C. Otherwise, the fish’s immune system will not respond effectively.
  • Salt Incompatibility: NEVER use NT Labs FMG Mix in a pond containing salt (Sodium Chloride). In fact, the combination is highly toxic and can be fatal to fish.
  • Sensitive Species: Do Not use with Orfe, Rudd, and Tench; Moreover, Sturgeon and Sterlets are highly sensitive and should ideally be removed during treatment.
  • Filter Health: After the treatment period, always conduct a partial water change and use a beneficial bacteria additive to aid in biofilter recovery.
