I got this for my 150 gallon chiclid tank and it kicks butt! I would recommend it to anyone looking for a good filter.

Highly recommend

Bought it to use on my turtle tank, works awesome, the water has neve been so clear, amazed at how quiet it is, was surprised at how big it was when it showed up, Love it, thinking about getting another for the fish tank.

The best of the best. You can't go wrong.

Overall the best canister on the planet but like most things there's pros and cons; it is an overpriced product but it is the best canister not just the flowrate gallons per hour turn, all the bells and whistles, durability, and in fact I believe it has less issues overall compared to other canisters less defective parts and the warranty , customer service and one of the top brands in aquatics.
