Review on Hydor 61300 Impeller Koralia Evolution by Meagan Owens

We purchased this accessory for our aquarium from the Pet Supplies category with high expectations, but it turned out to be a complete disappointment. Based on our own experience, the impeller did not perform how it was advertised and slowed down with time. The only positive aspect was the easy installation process. However, the consistent underperformance resulted in a negative impact on our fish and aquatic pets. Overall, we would not recommend this product to other aquarium owners.
