Seachem SulfaPlex

Seachem SulfaPlex is an effective and safe treatment for many bacterial, fungal, and protozoan infestations in both freshwater and saltwater aquariums.

  • Treats many bacterial, fungal, and protozoan infestations
  • Broad-spectrum antibiotic and anti-fungal medication
  • The most effective of the sulfa drugs in saltwater
  • Absorbed through gills

Seachem SulfaPlex is an effective and safe treatment for many bacterial, fungal and protozoan infestations in the aquarium. While it can be used in both freshwater and saltwater, and is particularly effective against the common bacterial and fungal infections of freshwater fish. It is also among the gentler antibiotics, and great for treating fish that are already stressed. It is easily removed with carbon and does not impair nitrification.

Types of Infections Treated: Parasitic, Fungal and Bacterial

Directions
Dosing in Water

Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon™ and Purigen™. Use 2-3 measures (included) per every every 40 L (10 US gallons). Repeat this dose every 72 hours for a maximum of 3 weeks.

Dosing in Food

SulfaPlex™ is most effective when used in the water, but it can also be added to the food. Feed the medicated food mix (recipe below) every day until the infection clears or up to 3 weeks.

1 scoop SulfaPlex™
1 scoop Focus™
1 tbsp food (preferably pellets or frozen food)
A few drops of water if using a dry food

To enhance palatability use with GarlicGuard™ or Entice™.

After Treating

When the treatment period is over, SulfaPlex™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank.

Active ingredients: sulfathiazole (69%). Inactive ingredients: excipients (31%)

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.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.
