Super Ick Cure water colour: an observation is not a residue test
Use a colour-change record without turning clear water into an unsupported compatibility claim.

Quick answer
API describes water discoloration and staining with Liquid Super Ick Cure. The appearance of the water alone is not a validated measurement of remaining medication or a clearance for returning invertebrates.
Keep the appearance note descriptive
The manufacturer page says the treatment can discolour water and stain aquarium materials. Its FAQ also discusses colour fading with time and light. These statements explain why appearance can change; they do not give a visual concentration scale for the product. Do not invent one from a photograph.
Record a comparable observation
A useful example is “water appeared blue-green under the same room light; photograph taken at 09:00”. Keep that separate from any chemical-test result and identify the test if one exists. A later photograph under a different lamp may look clearer because the viewing conditions changed. Record the difference instead of asserting that a chemical was removed.
Do not use clear water as return clearance
The product’s invertebrate restriction is a separate source statement. A lack of visible colour does not cancel it. Similarly, a stained ornament does not provide a concentration reading for the water. For a return question, describe the complete treatment and removal history and ask what evidence the manufacturer requires for the named livestock.
Preserve the label sequence
API’s instructions attach removal and carbon steps to a treatment sequence. Keep those conditions with the applicable label rather than using the first visual change as a new stopping rule. This guide does not choose a treatment duration, prescribe removal steps or certify that the system is free of residues.
Put it into practice
Your checklist
- Record colour as an observation with lighting and time.
- Keep appearance separate from measured chemical results.
- Do not treat a clear photograph as livestock-return evidence.

These links provide context, not product recommendations.
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.
