Hi, Im fishless cycling a small tank approx 30ltr its been cycling for a week but ive noticed the water is slightly cloudy its sort of misty if that makes sence! i have a Aqua-Flow 1 sponge filter running which came with the tank and im a little concerned it maybe the filter as i havnt heard of this make before Has anyone got any views on this make of filter or should i be looking at getting an internal filter which includes carbon (i belive the carbon clears the water?) any advice would be appricated as always
many thanks
