Great product

Pros: Received order promptly

Cons: None

This was my first time ordering from Marine Depot and am very happy with the filters. My order was almost 20% less than the store I usually purchase from.

Love Coralife

Purchased a Bio Cube for my husband as a beginner tank. Now, 4 tanks later I still love our first little BioCube 29. All of the products have met or exceeded my expectations.
