Why FishyMag says this

The manufacturer's own wording, quoted rather than paraphrased, so you can judge it yourself.

Shrimp

Manufacturer advises against

Fritz is unambiguous: remove shrimp before dosing. This is the product that disproves the most common shortcut in the hobby — it contains no copper and is still explicitly unsafe for invertebrates.

“Not safe for use with freshwater invertebrates including snails, shrimp, clams, other crustaceans or molluscs; remove these types of livestock before dosing.”

Marine invertebrates

Sources disagree

Fritz describes the product as safe for reef systems while also naming clams, crustaceans and molluscs among livestock to remove. Those two statements sit on the same page and cannot both be straightforwardly true for every marine invertebrate — confirm with Fritz before dosing a reef tank.

“Safe for reef and planted systems”

FishyMag reports what manufacturers say, quoted and linked. It does not diagnose illness or recommend a treatment, and it never infers that a product is safe from the absence of a warning — where no statement exists, it says so.

Formulations change. Always read the label on the bottle in your hand, and contact the manufacturer if your tank contains anything valuable or unusual.
