Excellent product and service

The sponge was exactly what I needed to hot rod my hang on the back filter. The delivery was quick and the customer service was excellent!

Great Product

I used these to replace the stock filter that came with my Marineland HOB filter. After weeks of using them, I can definitely tell the difference. They add so much area for good bacteria to grow. Excellent recommendation Cory.

this medium.

Works well

Tried this out after watching Corey’s video on filter hop ups. Works perfect just like he said!
