I have done this on a shrimp tank I had. It does work great! To help me with cleaning the pump due to it catching some dead plant material I got a sponge filter for a pre filter. It also gave the tank more media for the biological side. Making cleaning the pump itself only once in a while job.

I also do this for two bird baths I have and save me on buying a new pump every other year.
