Hello I have a 1000l tank with 150l sump, fx6 and xp3 with 7 clown loaches,motoro stingray, 2 bala shark , black ghost and more. All the fish in the tank have been there for over a year. i do 50% water change every week and only clean a part of the media every month. My fish are dying one by one without any sign first my black ghost nest day the motoro and today when I woke up my 4 biggest loaches where dead. i am really worried about the other fish. The only symptoms I can see are a little cloudy eyes on my small oscar and the smallest clown loach is swimming like crazy at the top of the water.
Does anybody know what this is?

Thank you

Do you have a water test kit (ammonia, nitrite, nitrate)? This is where to start. Pics of your fish and tank would help too.

First thing you need to do is pick up an ammonia test kit and Seachem Prime on the way home if possible. When you get home tonight test the water with all 3 tests. Prime can neutralize a bit of the ammonia, nitrite, & nitrate if this is the issue.

Second thing is a 30% water change tonight, and depending on your test results, you may need to do a 30% w/c everyday for the next week or 2. Your tank may have "biologically" crashed or insufficient. I personally would skip salt.

I would also recommend light feeding on every other day until things look better. How are the fish eating right now?

Plain and simple bio overload and poor water quality. More water changes,stop feeding until they are interested in feeding and check your water parmeters asap. Cloudy eyes is a perfect example your water is bad.
