MANUFACTURER QUESTION BRIEF — Seachem ParaGuard

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: Manufacturer advises against
Seachem's Directions open by instructing keepers to remove all invertebrates before dosing. Their FAQ is softer — they decline to certify the product as invert safe rather than forbidding it — but an instruction in the Directions outranks a hedge in the FAQ, so this is recorded as advise-against.

Biological filter: No evidence found
No statement from the manufacturer was found for this group. Treat it as unconfirmed and check with the manufacturer before dosing.
No supporting evidence recorded.

QUESTIONS TO SEND TO THE MANUFACTURER

Does your guidance apply to the exact bottle/market described above and to these groups: Shrimp, Biological filter?

Please clarify any cautions, conflicting wording or undocumented groups above. Does your answer depend on water dosing versus food or a separate bath?

Do products already used, filtration media or other equipment change the instruction? Please provide the applicable label or written directions.

I will attach photographs of the front/back label and provide exact species, tank details and product-use history when contacting you.

Ask about one exact gap with both sources attached

Guide updated November 9, 2026

What to check

Include the labelled product, market, pack, group and relevant setting. When two passages differ, show both instead of summarising them as a contradiction.

Worked situation

A useful question is whether a named FAQ for a liquid applies to the particular powder sachet you hold and the livestock you list. A broad question about the whole brand loses that distinction.

What to record next

Read the draft back before sending it yourself. Keep any reply with its date and scope; a reply for one formulation should stay with that formulation.
