Parasites are a natural part of every pond, and it's normal to find one or two even on healthy koi. What keeps parasites in check is your koi's immune system, good water quality, and proper quarantine practices. Despite this, parasitic infestations can still occur, especially during the season. That's where Koi Pharma® products come in – they are specifically designed to safely and effectively handle even the toughest parasitic infestations, keeping your koi healthy and protected.
