Water Conditioners & Medicine
Keeping your fish healthy starts with creating the right environment—and that means clean, safe water and proper care when your fish get sick or hurt. On this page, you'll find helpful information about common water conditioners and medicines.
To help you get started, I've created quick guides that you can download.
These guides provide an overview of each medicine, their benefits, and how to use them. I encourage you further check out the information on each product, as this short guide does not include the following: a description and any precautions/warnings.
Please note, this list includes only the products I've had firsthand experience with and is not every food these brands offer.
Additional Tips
-
Use the correct dosage: Always measure carefully—overdosing can harm fish.
-
Add conditioner during water changes.
-
Don’t treat without identifying the problem, as unnecessary medication can harm fish and beneficial bacteria.
-
Remove activated carbon from filters before medicating.
-
Quarantine sick fish if possible: This allows targeted treatment and prevents exposing healthy tank mates.
-
Monitor ammonia and nitrite levels during medication: Some treatments harm nitrifying bacteria.
-
Complete the full treatment course.
-
Increase aeration during medication.
-
Read labels carefully: Combining the wrong products can cause chemical interactions or toxicity.
-
Watch fish closely for signs of stress: Lethargy, gasping, darting, or clamped fins may indicate issues.
-
Store products correctly: Keep medications and conditioners in a cool, dry, dark place to maintain their effectiveness.
