Hello everyone I have had quite the trouble with my discus. I have not been caring for my fish as I should have been lately. The water literally turned brown. I haven't been able to test it. I've added a few things and been doing water changes 3 times a week. They have been doing construction on my waterline in my neighborhood too. I seriously think this has impacted my fish. I plan on getting a test kit this weekend. I've never seen them so ill. They have had gunk in their gills white spots white feces and it's really breaking my heart. I was still changing the water once a week. But I lost my ray angelfish and a few discus ray jumped out knew something was wrong I guess. I seriously think the water quality has decreased I used to drink the water out of the tap and now it is disgusting. To be honest when my tank was in its prime I drink three handfuls out and didn't get sick at all. my sump has the pad changed every 2 to 3 weeks and has 2 uv sterlizers. I know I'm not providing enough info and it may sound scatter brained but I'm seriously worried about my fish the antibiotics the one similar to zpac for humans has helped and the smaller discus are eating again. I've removed all substrate and plants and the larger discus are sick. Their anuses look swollen too which I've never seen same diet beef heart 2 or 3 times a day. I had a cracked phone screen and just got a new one. IF ANYONE KNOWS WHY MY WATER WOULD GET RUST BROWN FOR NO REASON PLEASE LET ME KNOW. I am going to clean out the ceramic rings at the bottom of the sump it has bio balls in the first chamber which I've never cleaned. The pump is still working great if you read all of this thank you. Please help me save my discus!
