plz correct me if im talking nonsense , the top is for the water to flow , the bottom is to clear the waste , if i seal the bottom how the waste gona get cleared ?

i should be following bro bai's idea when he mention , "Do a small partition like a L or U shape higher then ur soil level at the bottom which ur water will flow in ur IOS put a sponge in it to prevent soil or shrimp to be suck into it. Best is to silicon the partiton to prevent it from moving away when u take out the sponge for washing. " sounds ok hor ?
