Joan Reid –
The sponge fits perfectly in my Mc-20 filter. It effectively traps debris without clogging the system. Easy to clean and lasts longer than the previous sponge I used.
Claire Ross –
Works well for keeping my terrarium clean. The medium size is just right for my setup. I rinse it weekly and it still performs well.
Jacob Dyer –
Great filtration performance. No issues with shedding or breaking down. I’ve used it for over three months and it’s still in good condition.
Alexander Vance –
It fits the Mc-20 filter, but I noticed it doesn’t catch very fine particles. Might need to combine with another filter media for full effectiveness.
