Seachem Paraguard – 250ml 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).
This saltwater medication is particularly useful in hospitals and receiving tanks for new fish and whenever new fish are introduced to a community tank.
Features
- Eradicates ectoparasites and fungal, bacterial, and viral lesions
- Safer to dose than formaldehyde, formalin, and methanol
- Will not adversely effect bio-filter
Which species can take Seachem Paraguard?
All fish.
However, you can use Seachem ParaGuard for catfish, eels, loaches, rays, sharks and other types of scale-less fish, these species are more sensitive to this product.
Not safe for invertebrates. Thus, you shouldn’t use it if you have calms, corals, frogs, snails and shrimps.
Live plants will be stressed if you add ParaGuard in your fish tank. Therefore, it is advisable that you remove plants from the fish tank before treating your aquarium with this solution.
Why is Seachem Paraguard used?
Ichthyophthirius (freshwater) / Cryptocaryon (saltwater)
The fish’s body and fins appear to be covered in salt. Twitching, flashing, and other symptoms of stress and irritation are usually present. This name is applied to a number of parasites, but the symptoms are nearly identical. Ich is one of the most prevalent fish illnesses, and it is completely treated with care and attention to water quality.
Treatment Time: 14 days in freshwater, up to 28 days in saltwater
Piscinoodinium (freshwater) / Amyloodinium (saltwater)
Identical to Ich, but smaller and grey-gold in colour. It’s most common in saltwater, but it can also be found in freshwater. Although Velvet is not as frequent as Ich, the therapy is nearly comparable. It occurs more frequently in saltwater than in freshwater.
Treatment Time: 14-21 days
Fin rot: Infection with bacteria
Fins look shredded, ragged, or rotten. Fin Rot is frequently misdiagnosed as fin-nipping fish injury. This is caused by bacteria, not fungus, as the name implies.
Treatment Time: 7 days or until the infection is gone
Dactylogyrus trematodes (skin) / Monogenenean trematodes (gills)
Fish appear lethargic, flash against pebbles, and frequently gasp and exhibit other stress-related behaviours. Flukes are difficult to identify because the parasite cannot be detected until the illness has progressed to the later stages. Excess mucus production, twitching and flashing, and translucent spots are all signs of gasping, irritated, or red gills (advanced infections)
Treatment Time: 14 days or until the infection is gone
Instructions and dosages
Remove any invertebrates and any chemical filtration from the tank.
For every 40 L of water, use 5 mL (1 capful) of ParaGuard (10 US gallons).
As needed, repeat this dose daily as long as the fish show no signs of stress.
As a dip
ParaGuard is gentle enough to be used prophylactically (without causing obvious symptoms) if necessary, such as when receiving a new fish and before placing it in quarantine.
Use 3 mL per 4 L (1 US gallon) in a container separate from your main tank for 1 hour dips.
If the fish show no signs of stress, the dips can be extended.
Many diseases can be found in the display tank water as well as on the fish. Giving a fish a dip therapy won’t help if they immediately return to infected water.
