Hello, just wanted to say thank you to all of you. I noticed the other day that my tank was a little cloudy, before reading all of the posts and stuff here i would have just ignored it. My first thought was to check their water. Ammonia was 2 I immediately did a water change of 25% with my vaccuum and have been doing that for the past few days. Checked ammonia this morning and its back to 0 Not really sure what made it go up, but i have been a bad fish mom and have not gave them a good cleaning in like 2 weeks. I guess that was the cause of it. ) Well now thier water is clean and they are happy so I thank you for helping me to know how to save them. I will not neglect them again I have learned my lesson. Thank you all. Sandy
