Aquarium cloudy water after water change.?
I have a 55 gallon 10 year established aquarium that water turns cloudy after 5 gallon water change. This issue has been occurring for about a year. I did switch to LED lighting about a year ago and their has been an algae problem since adding LEDs. I have changed LEDs hours to 8 hours a day and I have added live plants which has reduced the algae. Water is still cloudy after water changes. I have a cascade filter and under gravel filter. Water tests are fine, no issues with water.
Any ideas why it's turning cloudy?
