Rated 4 out of 5 by from Great customer service I am new to using natural sand and it damaged my impeller and after a few emails with the techs at marinland the sent me a new impeller and the perfect fix for my problem, adding a nylon stocking to the pick strainers. And after trying it out for a month my filters are quite and the tank is crystal clear. I was so agrovated with the noise I am so glad I contacted marinland. Thanks gus and gals at marinland.

Rated 4 out of 5 by from Solves the "rattling" noise My tank is about 18 months old. The original Marineland pump/filter apparatus produced a loud rattling noise, almost from new. After a year or so I tried lubrication (vaseline) which solved this for a few days, but then the distracting noise started again. A new impeller, about a month ago, is quiet. Finally!

Rated 5 out of 5 by from Best price Bought these replacement impellers from marineland as they had the best price on the internet and couldn't find in local store. Also know that these are correct and OEM. Worked perfectly.

Rated 2 out of 5 by from Magnum 350 impeller I purchased an impeller and other parts it took over 10 days. In the mean I had to purchase another filter for my 55 gal tank. I also have had trouble with the impeller on my magnum 350 with rattling loss of suction and noise after about 3-4 weeks. I too have taken it apart several times to find the problem. Nothing in the impeller. So I ordered a new impeller and impeller housing to see if this resolves the problem. The impeller I received would not fit into the original magnet so now I had to order a complete impeller and magnet for 39 dollars they come as separate pieces not put together as a complete unit. I first searched for a complete unit without success. Now the delivery will take almost 3 weeks Oct 18-21.Glad I bought another filter as a backup. Would still like to get my magnum 350 working, it worked great at first.

Rated 1 out of 5 by from Sadly Disappointed I used to have the Emperor 400, 2 actually, and was extremely satisfied them. They were quiet, and the bio-wheels never stopped turning. They were so good, that I was able to stock my 120 gallon tank with 127 fish. I purchased the 350's, again 2, May 10, 2016. Both impellers and impeller shafts are deplorable worn. I've always had issues with the bio-wheels turning.I have 2 air-stones, in under-gravel filter lift tubes. Each stone is 24" away from the intakes. I have examined the filters, looking for sand, gravel, carbon, debris, and even checked for snails. No foreign matter found, but that's when I noticed that the shaft and sleeve were badly worn. The bio-wheels, I have done the same, checking for foreign matter, snails etc. Nothing found. I have had this issue with new filter cartridges, high water levels, and even checked the flow without the strainer on the intake without the covers on either. The bio-wheels will turn more often than not without my media in the filters.Not what I had expected :(

My 350 Penguin won't run again if power goes off. I had to lift a little part of the impeller housing in order to start again. Just a few days ago it happen again but this time won't run anymore. Impeller shaft broke in two and magnet got deformed. 

Asked by: Eamv2017
Sounds like you need a new impeller assembly and a power strip with surge protection. Also, be sure to clean the impeller very well every month or two. BREX

Impeller shaft in my 350 penguin bizarrely got stretched and thinned! Magnet also changed form and looks kind of triangular now. No idea what happen there!

Asked by: Eamv2017
This would be due to some sort of debris being caught in the well of the motor and wearing the shaft down. The most common culprit is sand. BREX

I have a Marineland Magnum 350 set up. This LOOKS like the right Impeller assembly. Could you verify that before I order it. Thanks

Asked by: Bozo123
Hi Bozo123, This is definitely NOT the correct one as this one fits the Penguin 350. You need: http://www.marineland.com/Products/aquarium-parts/Filtration-Products-and-Skimmers/Magnum-Parts/Impeller-Shaft-Assembly-without-Magnet-for-Magnum-350.aspx and if the magnet is also bad, you need: http://www.marineland.com/Products/aquarium-parts/Filtration-Products-and-Skimmers/Magnum-Parts/Magnet-for-Magnum-350.aspx.

Hi,wanted to know if you can remove the impeller from the lift tube? or is it one piece? This is on the penguin 350 hob

Asked by: Helnaak
It comes out. Remove the intake tube, then pull up the impeller housing. Once the housing is out, you will see the impeller attached to the underside of it. Just pull it out. BREX
