Used ParaGuard when my fish developed ich after a new addition. The treatment worked quickly without harming the fish or the filter. Water parameters stayed stable, and the fish recovered fully within a few days. Highly recommended for new fish introductions.

Tried it after noticing fin rot on one of my guppies. The product cleared the infection without any side effects. It’s easy to mix and doesn’t change the pH. A reliable option for external parasites.
