Used ParaGuard™ when introducing new fish to my tank. No pH changes, fish stayed healthy, and ich was completely gone within a week. Easy to mix and safe for filter use. Highly recommended for new fish introductions.

Tried it after a fin rot outbreak. The treatment worked well without harming my fish or altering water chemistry. The instructions were clear and the product was effective in reducing bacterial lesions.

Great product for treating external parasites. No formaldehyde means less risk to fish and equipment. Works quickly and doesn’t stress the fish like other treatments do.
