Marineland Emperor 400
purchased the 400 for our 55 gallon tank, it made a lot of noise so I called Marineland customer support and they sent me a new impeller. that did not help, called back and was told to return to store for another one. did that and the new one is even louder!! they both made a mechanical sound. I called customer support back and they said to just return it to the store, which I did, they could hear it in the background and agreed it was not normal.
has anyone else had this problem? it was so loud we had to turn the TV up almost twice as loud.
I replaced it with the Aqueon Quiet Flow 55/75 and it is sooo much quieter, I just needed to get something and this is what they had at the store. I like the Aqueon because you don't have to prime it- should the power go off it will draw water and continue to filter. we have several times when the power will go off for a few minutes (a good trade for country living!)
what are your thoughts on the Aqueon filter and are there some recommendations for another type?
