That has been tried... read in the begining about the "fart"...i think foam would clog after awhile (co2 tends to cuase organisms like bacteria or algae colonies to grow rapidly--ones that use co2--they might clog the foam after awhile.) The mesh seems to be the best option it does not have enough surface nooks to facilitate growth.

All my projects are still going strong...
