100% agree.. I use a super old aquaclear sponge I have from a hob.. I just leave it in the tank behind stuff.. been working great for YEARS

Great point !

Yeah I have scratch’s on my puffer tank from the magnetic scrappers. I use a similar sponge as you do now.

[@stubbsaquatics6080]

I have a few and you are so right.. I have scratched so many of my tanks

[@tylerphillipeck8017]

does the sponge work on rocks too?

@@tylerphillipeck8017 so if they are smooth river rock it should do fine. But any rough rocks it will just tear up the sponge.
