Rebecca Chapman –
Used Quick Clear after a water change and it cleared the cloudiness within 4 hours. My fish didn’t seem stressed and the plants looked healthy. Great for quick fixes between filter changes.
Cameron Taylor –
The water became noticeably clearer after adding a few drops. Works well for algae-related haze. I use it once a month during maintenance.

After stirring up the substrate during cleaning, the water turned hazy. Quick Clear solved it fast and didn’t affect my fish or plants at all.
