Seachem Laboratories ParaGuard Aldehyde Parasite Control 17 fl oz

Whether you are setting up a fresh quarantine routine or restocking a trusted favorite, it helps to have a dependable treatment ready for your finned friends. Seachem Laboratories ParaGuard in the 17 fl oz size is the brand's aldehyde-based parasite control in a mid-size bottle, a comfortable middle ground for regular keepers who want plenty on hand without committing to the largest jug. It is formulated to be both fish safe and filter safe, so you can care for your aquatic family while keeping your established setup intact.

• Aldehyde-based control (10% by weight) that Seachem describes as the only fish and filter safe aldehyde parasite product available for parasites on fish.
• Contains no formaldehyde and no methanol, unlike the formalin-based medications the brand contrasts it against.
• Will not alter pH, so the water chemistry you worked to dial in stays put.
• Made with a proprietary, synergistic blend of aldehydes, malachite green, and fish protective polymers.
• Seachem says it effectively and efficiently eradicates many ectoparasites, such as ich.
• The brand also notes it targets external fungal, bacterial, and viral lesions, such as fin rot.
• Particularly useful in hospital and receiving tanks for new fish.
• A reliable choice whenever new fish are introduced to a community tank.
• The 17 fl oz size suits ongoing care without the bulk of the largest bottle.
• Active ingredients are Glutaral and Malachite Green.

Keep this mid-size bottle in your fish-care kit so you are ready the moment a quarantine tank needs filling or your community tank gains a new member. Always follow the label dosing for your tank's volume, and remember these are the brand's described uses, not a promise of any cure. With ParaGuard on hand, you can give your underwater companions steady, caring attention.
