What the AI looks for in Fish Medication & Health Supplies

Diagnose first
Identify the symptoms (white spots, fin rot, bloat) before treating. Treatments are targeted, and the wrong medication can harm fish.
Remove carbon
Take carbon out of the filter during treatment. Carbon removes medication from the water.
Invertebrate safety
Avoid copper-based treatments with shrimp, snails and corals. Copper is toxic to invertebrates.
Quarantine
Treat in a separate quarantine tank when possible. This protects the biofilter and other tank inhabitants.
Dose by actual water volume
Calculate water volume excluding substrate and decor. Overdosing is easy if you use the tank's nominal gallon size.
