5The best money can buy!
By S. A DUNN
Years ago when I had many aquaria set up I tried both the Vortex diatom filter and the Magnum filter. The Magnum filter outlasted the Vortex filter by years, and the only reason I still do not have my magnum is that I sold all my aquaria stuff after a divorce years ago :(Now that I am in a good stable relationship, out comes the aquarium lusts again! I plan on getting the Magnum 350 here at Amazon soon. What makes the Magnum so special is that you can use it as a continuous filter media/activated charcoal filter in your large tank and it will sit there filtering the water for months with no upkeep. And when it is time to clean and replenish it's media, the operation is easy to do. AND, you can convert this filter into a diatomacious earth filter for those massive grungy tank cleaning jobs. This filter can remove all the crud from large tanks and still keep great water flow. Again, it is easy to clean out this unit after diatom use and re convert it into a everyday power filter.Once you buy a Magnum, it will last a lifetime.

4Works well
By M. Umberger
We got this filter for a turtle tank. Two red-eared-sliders. They make a big mess. It's a 40 gallon aquarium filled about half way. So this filter is way oversized. However, all the smaller mechanisms we used didn't do the job.This one seems to work fine. It keeps the water much cleaner than any others we have tried. A quick rinse of the filter cover every few days keeps it in top shape. It's fairly quiet too. That's important as it's in my daughter's bedroom.

4Great filter
By CarGuy
I've had a 75 gallon tank for about 30 years. This is only the 1st time I've had to replace the original Magnum I started with. I stared experiencing problems with the motor about 3 months ago, which I repaired, and then it stopped pumping as much water. I probably could have repaired that, as well, but felt it was probably time to get the latest and greatest. The main reason I stayed with Magnum, aside from my extreme satisfaction with my first one, is the ability to use generic charcoal/filtering materials. I took the opportunity to look at several other makes and all required the use of their own filters, pads, etc., all at high cost. Being able to use generic supplies keeps the long term costs down. Installation was a breeze. The reason for a 4 instead of a 5 rating is due to the slight difficulty of positioning the unit under the tank. Due to the quick release valves, the actual height needed is much higher than the actual height of the unit itself. I found that I had to "force" the hose to bend around the edge of the tank to go up the back. It seems to put a lot of stress everything and I'm concerned about the long term effect. Time will tell. In the meantime it works great, is quiet, and I am looking forward to another 30 years!
