From £10.99

Formaldehyde
Formaldehyde Bulk

Anti-Parasite Treatment for Koi

Treats: White Spot, Trichodina, Costia, Chilodonella.

When to use:

  • When fish show symptoms of a parasitic infection, including white spots along the fins and body, flicking and rubbing, gasping at the surface, or an opaque film over the body.
  • Formaldehyde is highly effective at treating parasites due to its ability to penetrate through the mucus layer, reaching those parasites which would otherwise be protected from alternative bath treatments.
  • Formaldehyde can be used in conjunction with Koi Care Malachite to treat protozoan parasites more effectively.
  • Suitable for koi only.

Do:

  • Test your water quality using Pondlab Test Kits.
  • Mix the appropriate dosage in a clean bucket of pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration for 5 days. Aerate the pond well during treatment.
  • If you feel a repeat dose is necessary, check your diagnosis carefully using the Diagnosis Tool on our website; a different medication may be more suitable. Allow 7 days and perform a partial water change before re- treating or treating with a different medication.
  • Always treat when you have time to observe fish and take appropriate action in the unlikely event of a bad reaction.
  • If required, mix with Malachite prior to adding to the pond, following the instructions above.

Warning:

  • Do not use with orfe, rudd, tench or sturgeon/sterlet.
  • Do not use if the water temperature is above 30°C.
  • Do not use in hot, humid, thundery conditions.
  • Do not mix medications, other than combining with Koi Care Malachite.
