Description
SulfaPlex is a sulfathiazole-based antibiotic with antifungal action, used for straightforward bacterial infections and for fungus on fins, mouth and eggs.
Quarantine tank only. It can be dosed to the water or bound to food with Focus for internal infections. Sulfa drugs are gentler on the biofilter than many antibiotics, but the quarantine rule still holds – a sick fish is easier to treat, and easier to watch, out of the display.
The 100 g size suits a regularly used quarantine system.

Shipping & Returns
- Equipment and dry goods ship at their own rate. Free shipping at $349 or more applies to qualifying livestock only — corals, fish, inverts and live copepods. The $10 box & handling fee is a livestock packing fee and does not apply to dry-goods orders.
- All sales are final on equipment and dry goods. We are a retail store, not the manufacturer.
- Register your product with the manufacturer and keep your receipt — their warranty is how a faulty unit gets replaced, and they are faster at it than a shop could be.
- Not sure who to contact for a warranty claim? Call us and we will point you to the right place.
