ALEGI Bio Sponge Filter Foam Cut to Fit Media 9.5"x3.5"x3.5", Replacement Insert Compatible to AC 110

This sponge was exactly what I needed. My Tidal35 water tank filter doesn’t have a typical suction tube like other filter so I couldn’t buy standard ready to use sponge filter to cover the suction from potentially sucking my fish or shrimp. I purchase this sponge, carved it out to fit my filter and it work wonderfully. I now don’t have to worry about my fish or shrimp getting sucked in. It’s the perfect fit for my filter and I got more value than what I spent on it.PRO: Affordable, easy to cut, doesn’t slow water down from going into the filter.CON: Only one chance to cut it correctly.

Perfect exactly what I needed for my pre filter

Funciona

Worked great for intake sponges on Fluval 207 and 407. I thought I'd make 3 skinny blocks but ended up cutting it in half and making 2. They're pretty big in the tank but I think will do a better job filtering with thicker walls. Rounded one corner with a serrated bread knife (don't tell my wife, but it did work GREAT) and they sit in the bottom corner of each tank. I left the cage on the intake tube sobthe little ball can still prevent backflow. (Aquarium Coop's videos show it taken off, I just didn't want to lose that function.) Don't overthink the size of the hole you'll need, just buy an uncut block like this and hack at it till the intake fits in. Cheap AND easy. Oh, and it did re-inflate just fine.

Love how big it is. I needed something to make my fountains bottom basin more quiet. It was just too loud for my condo, stuffed this in there and it worked perfectly!

What was delivered looks nothing like what is shown in the picture. It is a flat piece of foam barely 1/4 in thick. It is not the correct size to even fit in the holder, it is too big. This is definitely not a replacement filter for AC 70.

It came in such a small package I originally did not think it would work for my filter, but it plumps up nicely and does a great job.will order another when I no longer can get this one clean between water changes.

We have a pretty big aquarium and have 3 four stage filters on it. Helps keep the water clear and the fish happy. Glad they come in bulk so it is a little cheaper than the pet store.
