- A handle on the block for handling
- Designed for the Fluval Spec aquarium series
One foam filter block in the pack
The pack contains one replacement foam filter block. That single block is the mechanical stage described here: it traps large particles and debris as water passes through the foam.
Does this foam filter block fit your aquarium?
Check your aquarium before ordering. The block is designed for the Fluval Spec aquarium series, so it is the right shape for that line and not for other filter models. If your tank is a Fluval Spec and the filter takes a foam block, this replacement drops into that position. Look at the filter chamber in your Spec tank and compare it with the block. The fit depends on the model you own, so match the block to the filter that is already in the tank.
How the block handles and traps debris
The block is mechanical filter media, which means it catches large particles and debris. Foam of this kind collects the bigger material before it moves further through the filter. A handle is built onto the block, so you have something to grip when you lift the old block out and put the new one in. Several reviewers mention that it fits the original filter exactly, and a few comment that cleaning it is straightforward. Some reviewers also describe it as durable over time.
