Aquarium Pharmacy 💊🐟 [list]

I am not a pharmacist or a veterinarian, and wrote this for my own reference. Verify usage and dosage yourself. Using these carelessly will kill fish, kill plants, disrupt nitrogen cycles, or leave permanent stains. Some items are known or suspected human carcinogens. I tried to label warnings where applicable but I do not guarantee that all of them are labeled.
