Saltinthedesert Posted November 8, 2020 Share Posted November 8, 2020 I have this internal whisper filter (40i I believe) with lots of Endlers and yellow shrimp having babies. How do I modify the bottom to make it safe for the tiniest of critters? I’ve heard “put some foam on it” but where? What kind of foam? Specifics are helpful. I don’t want to restrict the flow and burn the motor. Thanks. Link to comment Share on other sites More sharing options...
Alesha Posted November 8, 2020 Share Posted November 8, 2020 I had one of those for a while. I popped the bottom off and added a piece of sponge behind the vent holes. I used this sponge and cut a small piece, then cut just a thin sliver of it. It didn't bother the flow at all. Sponge Pad Coarse WWW.AQUARIUMCOOP.COM Coarse Foam Reusable Fits all Filters Coarse sponge pad is a replacement for throw away cartridges in aquarium filters. Not only are the cartridges costly, they are also bad for the environment. Coarse sponge pads can be reused... 3 Link to comment Share on other sites More sharing options...
Mikey Walnuts Posted November 8, 2020 Share Posted November 8, 2020 You could get an Aquarium Co-Op coarse sponge, wrap it around the bottom and tie it in place. Or, if you have $20ish dollars to spend, get a sponge filter and air pump, let those run for a couple weeks and then pull your power filter. Then you have nothing mechanical that can suck up fry 2 Link to comment Share on other sites More sharing options...
shkote Posted November 8, 2020 Share Posted November 8, 2020 Congrats on all of your babies, how exciting! 🙂 @akconklin said it best with the sponge at the bottom. Aqueon actually has filters like this now specifically for shrimp with a thin sponge covering the slots at the intake, so I don't see restricted flow being an issue with that solution. 2 Link to comment Share on other sites More sharing options...
Fonske Posted November 9, 2020 Share Posted November 9, 2020 I mostly use internal filters and I cover them with nylon socks (new, washed with warm water only). No fry goes into the filters and shrimp love to forage on them. 1 Link to comment Share on other sites More sharing options...
