brcacti;1801203; said:Was trying to do a slow cycle with 2 fish I baught but it seems as it is not slow but fast with cloudy water now, both fish had fungus tail rot, one did not make it, dont know about the other one yet. I dont feed much but maybe I am way under filtered as only one fx5 is being used at this time so water turnover is 2 times hourly. Also its a new filter with new media so no beneficial bacteria to start with.
