Unlike highly toxic and difficult to use formalin based medications, ParaGuard contains no formaldehyde or methanol and will not alter pH.

It is particularly useful in hospital and receiving tanks for new fish and whenever new fish are introduced to a community tank. For use in freshwater or marine. ParaGuard is recommended for the treatment of certain diseases in marine and freshwater fish only. It IS NOT recommended for treating any style aquarium containing invertebrates, corals, crustaceans, or elasmobranchs (sharks and rays). ## Features - Bulk Pack Convenience: Includes three 500ml bottles for extended care. - Fish and Plant Safe: Ideal for use in both freshwater and marine aquariums. - Non-Invasive Treatment: Helps maintain aquarium balance without harsh chemicals. - Supports Aquatic Health: Assists in fostering a healthy environment for aquatic life. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002DWTIU6 | | ASIN | B002DWTIU6 | | Allergen Information | Allergen-Free | | Best Sellers Rank | #13,168 in Pet Supplies ( See Top 100 in Pet Supplies ) #97 in Aquarium Water Treatments | | Brand Name | Seachem | | Customer Reviews | 4.7 4.7 out of 5 stars (3,047) | | Date First Available | June 21, 2011 | | Department | Unisex-Adult | | Global Trade Identification Number | 00000116060301 | | Included Components | Seachem ParaGuard 500ml Bottles (3 Pack) | | Is Discontinued By Manufacturer | No | | Item Form | Liquid | | Item Type Name | Seachem ParaGuard 500ml Bottles (3 Pack) | | Item Weight | 454 Grams | | Item model number | 603 | | Liquid Volume | 16.9 Fluid Ounces | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer | Seachem Laboratories, Inc. | | Manufacturer Part Number | 603 | | Model Number | 603 | | Pet Type | Fish | | Product Dimensions | 2.44 x 2.44 x 7.62 inches; 1 Pounds | | Target Species | Fish | | UPC | 000116060301 | | Unit Count | 16.9 Fluid Ounces | | Warranty Description | Warranty | ## Product Details - **Brand:** Seachem - **Item Form:** Liquid - **Item Weight:** 454 Grams - **Liquid Volume:** 16.9 Fluid Ounces - **Number of Packs:** 3 ## Images ![ParaGuard, 500 mL / 16.9 fl. oz. - 603 - Image 1](https://m.media-amazon.com/images/I/51Xz+aPpRZL.jpg) ## Frequently Bought Together - Seachem ParaGuard, 500 mL / 16.9 fl. oz. - 603 - Seachem StressGuard Slime Coat Protection - Stress and Toxic Ammonia Reducer 500 ml - Seachem Prime Fresh and Saltwater Conditioner - Chemical Remover and Detoxifier 500 ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/3983084-paraguard-500-ml-16-9-fl-oz-603](https://www.desertcart.com.br/products/3983084-paraguard-500-ml-16-9-fl-oz-603) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-07-26*
