No, because it have low rpm, only high rpm gear motor can do that, u can use it for electric screw driver

As a screwdriver, can it drive screw into the wood without hole.

No, there is no harm or electrical sock for fish,it is safe

@@D0ITYOURSELF thanks bro

If you're really worried about the leaching of microplastics then I'd suggest not to use anything made from plastics in your tank. I'd be much more worried about the leaching of any remnant hydrogen sulfide off of that PVC that was produced when creating the holes using that wood burning tool.

🤣

It is an ordinary cleaning sponge.available at grocery store or small sofa making stores

​@@D0ITYOURSELFDamn! Where do I find one of these sofa making stores??

Thank you so much 😀

Have you actually had any "small critters" get sucked into one of your sponge filters? That would take some hellacious flow, not to mention some obnoxiously large hole in the sponge, like 2-3 PPI.

It's an ordinary cleaning sponge brother

Welcome 👍

Yes bro you are right,but this is very cheap one ,you make 4 sponge filter at the same cost you buy new one in aquarium shop....

@@D0ITYOURSELFYou can buy the pond size like the first one shown for under $3 on line. And if you want to increase the usefulness of it replace the riser tube with a one inch pvc tube cut off below the surface of the tank far enough to mount a power head on it. Now instead of pulling in fifty or so gallons an hour you can move 200 to 400 gallons per hour.

Thank you
