Sponges for DIY filter safe or unsafe?

  • We are currently upgrading MFK. thanks! -neo
the pot scrubbies from family dollar or dollar tree work well. like stated need to watch for bacteria resistant material and obviously no pre soaped sponges.
 
Those cellulose sponges are too dense to be good filter media plus they break down too quickly. I'd also be wary of possible chemicals.
