## Description

Bubblefin 4" Pre Sump Filter holder with 2 filter bags This is a Pre Sump Filter Holder It fits most of 20 Gal 40 Gal Standard US Tank The gap fitting on glass is about 22 mm. Filter holder with 2 filter bags. Check our stores for other aquarium accessories or equipment.

Review: Worth every penny - Building a sump for reef tank, and the sock holders are very good. Constructed very well fit perfectly on my rimmed tanks. It looks like it fits on rimless as well. Really happy with this purchase.
Review: Exactly as pictured and described. Works great! - It’s a great combo at a great price. The clear acrylic bracket includes two nylon set screws so it easily and securely attaches to the top edge of an aquarium sump with a plastic rim. They include two socks so you have 1 to capture large particulates while the other one is being cleaned, etc. The socks have a plastic frame that easily secures to the acrylic bracket. I liked it so much that I bought a second one for my other aquarium.

### ⭐⭐⭐⭐ Good holder, upgrade to different filter socks
*by N***D on September 3, 2025*

Holder is great, but the socks are pretty much useless. Upgraded to a much better filter socks. Holder fits perfectly for those as well and seems to be built really well. Just stick it in, screw it to the wall(wish the screws were better as they’re thin and go all over), and you’re good to go
