MANUFACTURER QUESTION BRIEF — Fritz Aquatics Algae Clean Out 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 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. Source (2026-08-16): https://fritzaquatics.com/products/fritz-algae-clean-out Biological filter: No evidence found Previously published here as compatible, citing a sentence about biological filtration. Re-reading the raw page found no such sentence anywhere on it — the quote came from a summarising fetch, not from Fritz. Downgraded to unknown, because a positive verdict with no source is exactly what this dataset refuses to carry. 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.
