Follow-up on the aquarium treatment evidence ledger

An audit of 56 saved wording entries, with a closer look at package labels and manufacturer documents for ten open entries.

Package follow-up ·

What the boxes and product documents confirm

We revisited all six conflicts and all four unverified entries from the original scan. DailyMed hosts the US box artwork supplied by Fritz Industries; hosting does not imply FDA approval. An information sheet or indexed FAQ is listed separately from the box it helps explain. No compatibility verdicts were reissued.

TreatmentWhat we could verifyDocuments checked
Expel-P
  • Biofilter: Two Fritz documents support the no-inhibition wording, but do not identify the package or revision behind the earlier warning. (Audit entry 67)
  • Tube worms and feather dusters: Unverified for aquarium exposure. The separate dip directions do not settle this question. (Audit entry 65)
Maracyn
  • Maracyn and erythromycin biofilter entries: The warning is verified for both US box sizes. The archived formulation and ingredient entries refer to the same product evidence. (Audit entries 69, 112)
Maracyn Two
  • Freshwater shrimp and snails: The box art does not substantiate the saved rows. The information sheet and FAQ differ in scope; the freshwater question remains open. (Audit entries 83, 84)
  • Coral: Unverified. Neither the boxes nor the FAQ identify corals as the animals tested. (Audit entry 86)
Maracyn Oxy
  • Scaleless fish: Unverified. The available Fritz documents do not substantiate the saved scaleless fish statement. (Audit entry 92)
FixIck
  • Live plants: Unverified. Neither Fritz source gives the saved plant species qualification. (Audit entry 96)
MetroCleanse
  • Gallon and litre figures; water and food directions: Verified the gallon figure and separate routes on both boxes. The 76 L figure appears on the sheet. No replacement calculator ratio was issued. (Audit entry 101)

What the original scan found

6 matched
Found in a manufacturer sheet or indexed copy. Punctuation differences do not change the wording.
40 differed
A related statement, different scope, or a rewritten instruction was available. This does not make it an exact match.
6 had conflicting evidence
The available material conflicts with the saved wording or exposes different scope between statements.
4 were unverified
The documents found in the original scan did not substantiate the saved statement.

Counts are saved entries, including entries reused across livestock or ingredient records. The original manufacturer URLs may still block direct retrieval. An indexed copy or alternate sheet is labelled as such; neither confirms what is printed on every bottle.

The formulation evidence dates are unchanged. No new compatibility verdict was issued. FishyMag withheld Maracyn Two and MetroCleanse calculations while the source differences are unresolved.

Source-by-source notes

RecordEntriesResultWhat we found
Algae Clean Out2Different wording or scopeIndexed Fritz directions retain the freshwater invertebrate restriction, with a differently punctuated list. Read source
Algae Clean Out1Different wording or scopeThe indexed page retains copper-free wording and a conditional plant statement, but the saved sentence differs. Read source
Algae Clean Out1Different wording or scopeThe indexed FAQ describes reef use when directed. It does not repeat the saved wording or remove the freshwater restriction. Read source
Coppersafe4Different wording or scopeIndexed Fritz wording still addresses invertebrates. The product information sheet separately describes plant and snail effects; neither is the saved sentence. Read source
Coppersafe1Different wording or scopeThe manufacturer sheet says the product may harm plants. The saved table wording was not found in the sheet. Read source
API Liquid Super Ick Cure1Different wording or scopeA different size listing has opposing snail answers in its retailer FAQ. The saved sentence summarizes them. API’s own liquid directions remain the primary source. Read source
PraziCleanse2Different wording or scopeThe manufacturer sheet uses different general invertebrate wording and specifically excludes tube worms and feather dusters. Read source
PraziCleanse1Matched in manufacturer sheetThe saved plant and other-invertebrate sentence appears in the manufacturer sheet, immediately before its tube worm and feather duster exception. Read source
ParaCleanse5Different wording or scopeThe indexed product page uses separate broad invertebrate and plant statements. The saved chart line about snails was not found in that copy. Read source
Expel-P3Matched in manufacturer sheetThe manufacturer sheet contains the saved sentence about the filter, plants and other invertebrates. This does not resolve separate cautionary wording. Read source
Expel-P2Different wording or scopeThe indexed directions qualify some snail species. The available copy phrases that qualification differently. Read source
Expel-P1Not establishedThe available sheet describes a separate coral dip, but did not establish the saved tube-worm and feather-duster wording for aquarium exposure. Read source
Expel-P1Conflicting evidenceIndexed Fritz directions say nitrification is not inhibited. The saved record also quotes earlier wording saying it may be. Direct retrieval remains blocked. Read source
Expel-P1Different wording or scopeThe sheet gives the ten-gallon ratio and a next-week repeat, but omits the saved litre equivalent and phrases the schedule differently. Read source
Maracyn2Conflicting evidenceAn indexed Fritz FAQ describes most nitrifying bacteria as unaffected. That does not match the saved caution. Read source
Maracyn2Different wording or scopeThe sheet addresses invertebrates broadly, without reproducing the saved snail-specific table wording. Read source
Maracyn1Different wording or scopeThe indexed directions describe possible yellowing in some sensitive plants; they do not reproduce the saved row or its pond-plant wording. Read source
Maracyn1Different wording or scopeThe packet shown in the maker’s sheet names fresh and salt water. The original chart line was not available. Read source
Maracyn1Different wording or scopeThe sheet uses a ten-gallon instruction, but does not repeat the saved parenthetical litre figure. Read source
Maracyn Two2Conflicting evidenceThe indexed directions use broad invertebrate wording. A separate Fritz FAQ says it has no data on freshwater invertebrates; the snail-specific line was not established. Read source
Maracyn Two1Different wording or scopeThe indexed page notes possible yellowing in sensitive plants, without repeating the saved pond-plant row. Read source
Maracyn Two1Not establishedThe indexed FAQ refers to tested reef animals but does not identify coral species or reproduce the saved coral line. Read source
Maracyn Two2Different wording or scopeThe indexed page mentions possible nitrification effects; its bacteria replacement advice appears in a separate combination FAQ, not as the saved general instruction. Read source
Maracyn Two1Different wording or scopeThe manufacturer sheet separates the first day from later days. The saved single ratio represents only one stage; arithmetic is withheld. Read source
Maracyn Oxy2Different wording or scopeThe indexed page gives broad invertebrate wording with a starfish exception. The saved snail-specific chart row was not found. Read source
Maracyn Oxy1Different wording or scopeThe indexed FAQ qualifies the plant statement by mentioning possible yellowing in some finer-leaved or sensitive plants. Read source
Maracyn Oxy1Not establishedThe available manufacturer sheet did not establish the saved scaleless-species statement. Read source
Maracyn Oxy2Different wording or scopeThe manufacturer sheet excludes starfish and related species in prose rather than the saved table wording. Read source
FixIck3Different wording or scopeThe indexed directions explicitly name snails among excluded invertebrates, rather than using the saved table wording. Read source
FixIck1Not establishedThe indexed copy did not establish the saved plant-species qualification. Read source
FixIck1Different wording or scopeThe indexed page expressly excludes coral, but does not reproduce the table row. Read source
FixIck1Different wording or scopeThe indexed product page addresses scaleless fish in the directions rather than in the saved chart form. Read source
Expel-F2Matched in indexed copyThe indexed manufacturer text contains the saved macroalgae and coral qualification, with a punctuation difference. Read source
Expel-F1Different wording or scopeThe indexed product directions retain the same reference volume and preparation context, but the saved sentence is not reproduced. Read source
MetroCleanse1Conflicting evidenceThe manufacturer sheet uses a different litre figure and separates broadcast from food directions. No replacement calculator ratio is provided. Read source
