Marineland PC0350C Magnum 350 up to 100-Gallon, 350 GPH

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.

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.

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!

4 out of 5 stars since I have not cleaned the media & it has been running for only 3 days

Pros: Strong filtration, separate filtration & mechanical construction, quiet

Cons: Professional setup required, many parts & assembly (so follow instructions carefully & watch youtube demonstrations).

This canister filter is not ready to go out of the box. Don't expect that. Have realistic expectations of taking about 2-3 hours to carefully setup and you will not be dissapointed. Posted pictures of before tank (not cleaned on purpose) & after

A long time fan of Marineland products the Magnum 350 caught my interest because it can double as a water polishing unit that uses cartridges.I placed a call to Marinland and found out the polishing cartridge will remove particles as small as 10-15 microns. For true water polishing the only filter in the world that can remove particles as small as one micron in size is the Diatom by Vortex renowned for it's ability to filter out pathogens and parasites like ich.

As a primary filter for your aquarium I can't recommend the Magnum.It's limited to mechanical filtration only, the chamber you use for activated charcoal is far to small to hold enough biological filter media to colonize enough nitrifying bacteria.The filter has poor build quality all the way around.It can't hold a candle to the solid craftsmanship you would find with say, eheim. It's also sub par to anything put out by Fluval.

Problems happened fast after the first use. The impeller is quirky it starts and stops and is a constant battle. You're forever having to adjust it and the entire assembly. It can leak as well Especially if you haven't applied enough silicone to the head gasket. It's also loud and it's a noise like a coffee grinder.

Quick Specs

* Certified Flow Rate of 350 GPH

* No water bypass

* Good for tanks up to 100 gallons

* Can convert easily from continuous filtration to water polishing

* 2 year manufacturer's warranty

* Polishing cartridges can be cleaned and re-charged with bleach solution

At the list price around $329.99 I wouldn't give it a first glance not to mention a second one. But to find it here on Amazon for a mere $94 it's a decent deal.The polishing cartridges sell for $19.99 just about everyplace I looked.However you can find them here on Amazon for $9.00

This isn't a filter for everyone. It should only be the choice of the hobbyist who wants water polishing from time to time.And who understands the issues and headaches that come with owning and maintaining one.
