Happy Lucky Fish Club

Disclaimer (read this): This site is a hobbyist synthesis — drawn from product labels, books, and experienced keepers. It is not veterinary diagnosis or a prescription. Species differ. Verify every dose on the current product label. Weigh salt on a kitchen scale (teaspoons are a last resort). When fish crash, parasites are unclear, injectables or culture are needed, or mycobacteria is on the differential — escalate to an aquatic veterinarian. Full text on the About / Disclaimer page.

Practical freshwater hobbyist reference. Blunt where it needs to be. Not a vet clinic.

Salt, in one line

Use a kitchen scale. Target 0.1% = 1 ppt = 1000 ppm ≈ 3.8 g salt per US gallon. Teaspoons are approximate only — last resort if you have no scale. Full table on Treatments.
