What is the role of a chemical filter in an aquatic system?

• A. Remove dissolved chemicals such as chlorine
• B. Remove solids by physical trapping
• C. Increase water pressure
• D. De-oxygenate water

Answer: (A)

Chemical filtration works by using adsorbent media, like activated carbon, to remove dissolved chemicals from the water. This includes chlorine and chloramines added to tap water, as well as various organic compounds that can affect taste, odor, or harm aquatic life. By pulling these dissolved substances out, the filter improves water quality without physically trapping particles or altering oxygen levels. This is why removing dissolved chemicals is the key role. Solids are taken out by mechanical filtration, which captures particles as water passes through filter media. Increasing water pressure isn’t a function of chemical filtration, and de-oxygenating water isn’t something chemical filters are intended to do; in fact, maintaining adequate oxygen depends more on aeration and water movement.
