Why Use API Accu-Clear?

Cloudy water is often caused by suspended particles that are too small for aquarium filters to capture efficiently. API Accu-Clear binds these particles together, making them large enough to be removed through normal filtration.

Cloudy water can be caused by bacterial blooms, disturbed substrate, overfeeding, or insufficient filtration. API Accu-Clear helps remove suspended particles, but maintaining proper filtration and regular water changes is essential for long-term water clarity.
