Save what lives in your tank once, then check any treatment against all of it at once.
What you’ll need
Use your real water volume, not the size on the box. Work it out.
Saves automatically to this device as you type
Tell us what you keep
Select at least one group above and every treatment in the database will be checked against it.
Every verdict comes from the manufacturer of that product and is quoted on its page. FishyMag does not diagnose illness or recommend a treatment, and “not addressed” never means safe.
Checking a single product against a single animal is the easy case. The hard case is the one people actually have: a planted tank with shrimp, a couple of nerites, and a fish that needs treating — and a shelf of products whose labels each address a different subset of that.
Save what you keep and every one of the 8 formulations in the database gets checked against all of it at once, drawing on 41 manufacturer-sourced verdicts. Results are grouped worst-first, so a warning can never hide beneath a run of green ticks.
The profile stays on your device and carries into the other tools, so you only describe your tank once. The calculator will work out your real water volume if you do not know it.
