    Only in one of my tank due to ph drop all my fishes died over night. Then i did 100% water change and check the ph it was 7

    Then at night I checked again... It has gone down to 4 now..

    There is some kind of yellow foam is floating on water and water is smelley. There is no fishes.

    What could be the problem

    Is there a lot of decomposing matter in your substrate or filter?
