Becomes fert. Leave it.
If you do not like it you can use fine tubing like air tubing or just a bit larger to vacuum the debris with minimal disturbance to the plants. It is slow, but that is the point: Slow water movement, and small tools (in this case the fine tubing) next to the plants do the least damage.
I would keep my hand wrapped around the part of the tubing that is draining to the bucket and be ready to pinch it off or fold it to slow or stop the vacuum in case of a problem.
