The foam block fits perfectly in my Spec 5 G and holds debris well. I clean it every two weeks and it keeps the water clear. Easy to install and lasts longer than the original.
Alison Dyer –
Works great with my EVO 5 G. The foam traps large particles effectively and doesn’t clog easily. I noticed a cleaner water flow after installing it.
Abigail Walker –
Replaced the original foam in my FLEX 9G and it fits snugly. The filtration is much better now, especially with plant debris and fish waste.

Good quality and fits exactly. I use it every 4 weeks and it maintains water clarity. Slight odor after installation, but it fades after a few days.
