MANUFACTURER QUESTION BRIEF — Seachem NeoPlex

Database market: US. Record checked: 2026-08-16.

My bottle / market / label revision: Not supplied — check the bottle before relying on this record.

Other products already used: Not supplied; no combination assessment has been made.

Shrimp: Sources disagree
Seachem contradicts itself on this product. One passage says NeoPlex is well tolerated by invertebrates with delicate species possibly stressed; another instructs keepers to remove all invertebrates as extremely sensitive to medication. Both appear on the same page. Seachem also suggests medicating via Focus-bound food instead of the water column, which reads as an acknowledgement of the risk.

Biological filter: Manufacturer states compatible
Seachem lists NeoPlex as having minimal impact on the biological filter.
