Seachem ParaGuard

Seachem ParaGuard is used to eradicate ectoparasites and external fungal, bacterial, and viral lesions in fish while being safe for fish and filters.

  • Eradicates ectoparasites and fungal, bacterial, and viral lesions
  • Safer to dose than formaldehyde, formalin, and methanol
  • Will not adversely affect bio-filter

Seachem ParaGuard is the only fish and filter-safe aldehyde-based (10% by weight) parasite control product available (for parasites on fish). Unlike highly toxic and difficult-to-use formalin-based medications, ParaGuard™ contains no formaldehyde or methanol and will not alter pH. ParaGuard™ employs a proprietary, synergistic blend of aldehydes, malachite green, and fish protective polymers that effectively and efficiently eradicates many ectoparasites (e.g. ich, etc.) and external fungal/bacterial/viral lesions (e.g., fin rot). It is particularly useful in hospital and receiving tanks for new fish and whenever new fish are introduced to a community tank.

Types of Infections Treated: Parasitic, Fungal, Bacterial and Viral

Directions
Dosing

Remove all invertebrates from the tank as well as any chemical filtration. Use 5 mL (1 capful) of ParaGuard™ for every 40 L (10 US gallons). Repeat this dose daily as required as long as fish show no stress.

ParaGuard™ can also be used as a medicated dip. For 1 hour dips, use 3 mL per 4 L (1 US gallon) in a container separate from your main tank. Dips may be extended if the fish show no evidence of stress. Keep in mind that many diseases linger in the water as well as on the fish. Giving a fish a dip treatment does no good if they go right back into infected water.

Quarantine

This is a tank set up in order to monitor and medicate new fish before they go into the main tank. ParaGuard is gentle enough to use prophylactically (without visible symptoms) if needed. Quarantine times vary, but we generally recommend 2 weeks of treatment with ParaGuard™ to clear out any possible external infections.

Sensitive Fish

Some fish are more sensitive to medications than others. Eels, loaches, rays, sharks, and many others are well known for their sensitivity to all kinds of medications. If you suspect that your fish may be sensitive to medications, it is just fine to start with a partial dose and build up to the full dose over several days.

Not recommended for reef aquaria. As an alternative, use Seachem’s MetroPlex

WARNING! Do not eat, drink, or get into the eyes! In case of eye exposure, promptly & thoroughly wash eyes with water & seek medical attention.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.
