## Description

Review: Thick, Durable, and Works Well - They are thicker than expected and not flimsy at all. The sponge feels durable and holds its shape well once installed. Plenty of surface area for filtration and beneficial bacteria, and they do not collapse or compress easily under flow. Overall, solid filter pads that feel like they will last.
Review: Awesome cost effective way to ditch cartridge filters! - I purchased this foam to use in my emperor 450 hang-on-the-back style filter, in conjunction with my media holding baskets and ceramic rings down the main pickup tube tray. Between the ceramic and open cell foam media there is plenty of area for biologic filtration, and in separate sections so you can clean them in waves and not knock out all the beneficial bacteria like when doing them all at the same time. The media does an OK job at trapping the physical debris during its mechanical filtration, however i prefer to throw a smaller cell filter before that i pull out more frequently and wash off to get the bulk of the junk while leaving the larger cell foam to focus more on biological filtration. The last element you are missing from the over-priced cartridge filters is the chemical filtration media included in the cages behind the floss layer. The 400/450 models i own offered cages that could fit behind the filters, which i use on one or both sides to help get some flow over carbon or whatever other media i am running (maybe after a medical treatment or whatever) and when not in use i just slam another wedge of foam in there. The smaller ones i just get a filter bag, throw some of the carbon pellets in there and drop that on top of the foam part for the final stage in the smaller tanks. Overall, its just a hunk of open-cell-foam but with a bit of handy work and an open mind this could save you hundreds on OEM and store brand replacement filters you just throw out once you are done with them. Just google around about making your own fishtank filters and there is a wealth of info - just remember to start simple and expand from there and you will do fine! Cutting the material can be tricky, and the sheet provided is large enough to make a few filters but not huge by any means. I got about 6-8 filters out of the single sheet which ranged from my larger emperor 450/penguin 400s down to some blocks cut for my smaller 10g fluvial filters - even have some in the submerged power-head type filters in the cichlid tank! In addition to the mechanical and bio

## Features

- Improve water quality: the aquarium sponge can filter out many particles in the aquarium or fish tank, avoiding residues and reducing the mortality of fish, which can increase the solubility of oxygen in water
- Safe and healthy material: the black aquarium filter sponge is made from bio sponge that is safe to use in seawater or freshwater fish tanks and glass containers; You can clean the filter foam easily, and use it repeatedly
- Support to trim: measured about 9 x 9 x 1 inches, the bio media sponge can be trimmed into the size that you need; The included 3 pieces of aquarium filter sponge can be cut into some small sized filter foam that fit for your aquarium filter
- Coarse sponge: the 30 PPI black sponge sheet provides more surface area to catch the floating debris so that help to keep the aquarium water clear, which can also avoid debris blocking the pump tube
- Wide application: the bio media sponge is suitable for freshwater aquariums, seawater aquariums and coral reef aquariums; You can install one piece of filter foam to improve aquariums water and give fish, little turtles, or shrimps a cozy environment to live

## Questions & Answers

**Q: Can this be used in place of the 2 inch thick foam sheet I use now?**
A: Not sure what your application is.  Not sure if this will work.  I use this foam as a pre-filter for a bird bath. I cut a sheet into 3 pieces about 2” wide and placed them into an upside down plastic box. The box has holes on each side and this foam works PERFECTLY keeping the water clean for about 3 weeks. A brick on top of the box seals the foam against the bottom and prevents floating.
