Turn filter off. Pour the liquid into it directly quite slowly, so none runs over the outflow.

^^^ So let me make this clear, I turn off the filter canister, pop the top lid off, take the water containing the BB, and pour it into the filter canister? I have a big long filter pad on one side, and the 3 stage trays on the other side which is a sponge, ceramic tubes, and a Carbon bag on the very top tray. Did I understand you right?

thanks again!
