I just set up a new tank, I used the african cichlid sand from carib-sea. Instructions said not to wash it.. The tank has been running for over 72 hours now and the water is still cloudy. I was thinking of doing a water change, but I also have started my cycle with pure ammonia 2 days ago. Will changig the water and cleaning out the filter sponges screw up my cycle? Or should I just wait it out?
