Activated carbon and aquarium medication: do not confuse media with the whole filter
Use KanaPlex’s water-dosing directions to distinguish a chemical-media restriction from a biological-filter statement before changing equipment.

Quick answer
A direction to remove chemical filtration is not an instruction to switch off an entire filter. Seachem’s KanaPlex water-dosing directions name chemical media separately from UV and ozone equipment. Identify each component and follow the exact formulation’s instructions.
Read the named component, not just “filter”
Seachem’s KanaPlex water-dosing section identifies MatrixCarbon and Purigen as chemical-filtration examples. Its overview separately addresses the filter bed. Those are different statements with different scopes. A biological-filter compatibility statement does not cancel a chemical-media restriction, and an equipment restriction does not by itself establish a biological-filter verdict.
Make a component inventory before changing anything
Write down the filter model and each installed component using the name on its packaging. Include mixed cartridges, resins and any separate UV or ozone unit. Do not assume a cartridge contains only one kind of material because its outside looks like a sponge. If its composition is unclear, mark it unknown and consult the equipment maker. Your inventory should describe what is installed now, rather than a standard configuration shown in a product photograph.
Keep the before, during and after instructions distinct
Note whether each instruction applies before, during or after treatment, and how the product is used. A statement about removing medication after treatment is not permission to leave every medium installed during treatment. Ask the manufacturer about the actual component if its label name differs from the examples. Log any completed equipment change with the time and reason; a checklist is a record aid, not an automatic instruction to dismantle filtration.
Put it into practice
Your checklist
- Inventory individual media and equipment by their actual names.
- Keep chemical-media guidance separate from biological-filter claims.
- Record the route and treatment phase attached to each instruction.

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.
