Does every condition in an aquarium recall notice match?
Complete a recall-scope matrix for three fictional aquarium packs while preserving unreadable identifiers and the notice’s separate action instructions.

Worked evidence example · Not a clinical review or treatment recommendation.
Quick answer
Check every scope condition in the original notice. In this fictional example, item AX-20 with lot L42 in Market M matches the stated scope; lot L44 does not match its lot range; an unreadable lot remains unresolved. A brand match alone cannot complete the review, and being outside one notice is not a safety clearance.
Figure data and explanation
Entirely fictional notice and packs. The three outcomes depend on the supplied item, lot and market conditions together.
- Complete match
- P meets all three invented conditions.
- Outside stated scope
- Q misses this notice’s lot condition.
- Missing identity
- R cannot be resolved from an unreadable lot.
A completed scope matrix shows exactly which condition establishes or prevents a match.
Copy the notice’s scope before inspecting the pack
Real notices do not all use the same conditions. The CPSC’s April 21, 2011 Marineland heater notice, for example, identifies specific model numbers and notes that some products were sold in starter kits. Do not invent a lot requirement if the actual notice uses models, or overlook a component because it arrived inside a kit. That historical notice is a real source; the pack-and-lot example below is entirely fictional and does not announce a new recall.
Complete the three-pack review
The invented notice applies jointly to AX-20, lots L41 through L43, supplied in Market M. Its stated action must be read separately. All identifiers below belong to a teaching case, not an actual manufacturer, market authorization or recalled supply.
| Received pack | Item condition | Lot condition | Market condition | Completed scope finding |
|---|---|---|---|---|
| P | AX-20 matches | L42 is within L41 to L43 | M matches | All supplied scope conditions match |
| Q | AX-20 matches | L44 is outside the stated range | M matches | Does not match this notice’s lot condition |
| R | AX-20 matches | Lot cannot be read | M matches | Unresolved; do not infer a lot from the carton beside it |
Keep scope, action and general suitability separate
For P, preserve the exact notice and its applicable action rather than substituting advice from a seller review. For Q, the finding is limited to this notice; it does not establish general product suitability or rule out another notice. For R, ask the issuing organization how the actual pack can be identified when its lot is unreadable. Keep photographs, purchase details and any component identity together. If a real notice instructs immediate action, follow its official instruction and current contact route rather than treating this worksheet as a reason to postpone it. The CPSC notice’s original remedy text must not be presented as a guarantee that a historical contact number or remedy process remains unchanged today.

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.
