Cloudy water on established aquarium doesn’t go away

[misakiesc]

Hello everyone,
I’ve had this 10 gallon for about 1.5 months set up (5 white skirt tetras and 4 cherry barbs) and this past week after refilling up the aquarium with about a cup of water since it had evaporated the tank has gotten cloudy. I’ve checked water parameters and it’s all good + all my fish are doing great. It’s just the water that’s slightly hazy and it’s been rather annoying to keep looking at. I’ve tried to use a water clear liquid as well as clean my filters and add extra filtration but it doesn’t seem to make much of a difference. What could I do to fix the foggy water?

Do you have a picture? That might help diagnose any problems. Without that, my best advice would be to do a large water change and wipe off the viewing side of the glass.

You need to do regular water changes. Simply topping up water that has evaporated isn't nearly enough.
I know you've said it is a 10 gallon tank, but what dimensions?
What is your filter arrangement?

Is the cloudiness white cloudy, or green cloudy?

I’ve checked water parameters and it’s all good

Can you tell us the exact numbers for ammonia, nitrite and nitrate please. Many stores and some test kits say readings are OK even when they are not.
The only good level for ammonia and nitrite are zero, and nitrate less than 20 ppm.
