180 litre tank,built in filtration system,approx25 fish none bigger than 1 - 2 inches,bogwood, live plants,granite, gravel.
The tank has been running fine for 10 months with regular maintenance and all water quality tests OK. Now the tank is clear a.m. but gets cloudy in afternoons, then clears again by nightfall. Never crystal clear though as before.Anyone any ideas please ? Have tried turning lights off and replacing all but bacteria pads, also partial water change. Help !!
