Collection: Powder Antibiotics

Fish Antibiotics in raw pure powder form


The Pure Powder Fish Antibiotics that we sell are 98-99% pure powder fish antibiotics that come in bulk jars and do not contain any fillers or carriers. Thomas Labs Pure antibiotic powders come in different strengths based on the type of antibiotic and each is labeled with a “per level scoop” dose amount. Pure Antibiotic Powders are helpful for dosing and administering fish antibiotics to fish tanks that are not standard size and may container smaller or larger fish than average fish tanks. They are also useful in situations that require very specific dosing measurements. Because they are in bulk powder form they often cost less than the same medication in pill or capsule form.
