I have a Tetra internal HOB filter, the bottom of the filter is about 4" across, any ideas to slip something over the top of the the filter so that small fish wouldn't get sucked in? Any thin foams or other items available? I have an Eheim canister filter, covered the intake with foam for a fluval and that was great but I'd like to cover this filter too. Thanks!

I'm looking for something that fits over the bottom of the actual filter since the water is taken up from the bottom, which is about 4" across. No pipe in this case. I have a filter over my small intake pipe on my Eheim canister just like yours and it's awesome so was hoping to make something similar to cover the bottom of the Tetra filter. I may have some baby fish coming and don't want them getting sucked into the filter.

If the true need for this foam is to keep fry out you'd likely be better off buying some coarse foam and cutting it to fit. Amazon likely has one of the larger collections.
I wondered about using thin filter sponge such as used with vacuums or air intake furnace filter? Would this filter have chemicals that I could just rinse off? Then maybe hand sew a filter “sock” that fits over the bottom of the filter? I saw a link from a 2016 post where someone said they did it this way but I’d like to be sure it’s safe.

Your safest bet is to use sponge that's designed for aquariums. Hand rinse with some tank water and you're golden. Get course sponge to avoid stealing pumping force from your filter.
