Hi everyone. We just got our first aquarium and two African Cichlids. We got the tank set up Friday and brought our fish home yesterday. The heater is working fine and the filter looks like it's working fine but this morning we noticed the water is already a little cloudy. Is this normal or does it mean the filter isn't working properly? The fish seem to be adusting well and don't seem to be in any sort of distress. They told us at the pet store that we need to change the filter once a month and change the water (not all of it) once a month but not both on the same day. Besides feeding them daily and cleaning the tank, is there anything else we need to be doing on a daily basis? The tank we got is the TopFin starter kit if that makes a difference. We know we'll have to upgrade to a bigger tank soon when they start growing, so don't worry. We're on top of that. Thanks in advance for any advice anyone can offer.
