Excellent Filter System

I had the system for 3 years now and it is very simple to operate. Easy to clean and components are readily available. Be warned! If you have no experience with filtration systems nor the basic concept of how they work then move on to a different make. There is no Magniflow for Dummies manual and there doesn't need to be. If your looking for a filtration system that will keep your tank crystal clear for years to come then you are at the right place. Congratulations.

Literal filter GOD

I bought two of the 360 filters two years ago and both have worked great for two years. The impeller media and valve block are all super easy to replace and don't cost too much. This filter is the best thing that's happened to my turtle tanks and can clear up a 4 month dirty tank within 48 hours to clear water. They can cause frustration when trying to reassemble them but each time they start up they work as good as they first did. I don't know why so many people have issues with these mine have only ever worked great and I have gotten friends to purchase these with great success as well.

Magniflow 250 is great.

Replaced a HOB unit that was underperforming for my tank. Having done no research I headed to PetSmart and found the Magniflow 250 at a reasonable price. I followed the instructions and it took 15-30 seconds for me to prime. It works very well and exceeds my expectations with how well it works and the amount of noise it produces. It produces a very soft hum unlike my HOB it's almost silent. Very happy with this product.
