## Customer Reviews

### ⭐⭐ Not suitable for aquarium use
*by E***Y on February 18, 2018*

The piece of foam I received was NOT reticulated foam, shipped from China and not suitable for aquarium use. More like common furniture/packaging foam. It was also not the thickness stated in the listing. Buyer beware!

### ⭐⭐ Too thin for our filter grid and not the thickness the ad claimed.
*by A***N on March 2, 2018*

The product seems fair and had no odor and has good size pores to use as a pre filter. However, the item they sent is not 2.5 cm thick as their ad states, it is only 1.8 cm thick and is not the correct thickness to fill my filter grid slot so it can come out to easily and just float around in the tank. The pad is useless if it is not the correct thickness as advertised. The seller will not respond now.

### ⭐ Beware of infinite amount of specks of loose sponge coming out of the material.
*by A***R on December 3, 2017*

I cut a piece to use for my aquarium filter.  However, rinsing it, I noticed black specks from the black sponge kept coming out of the sponge despite soaking and rinsing for several days/weeks.  This will pollute the tank water.  I could not use the product.
