Best Power Filter
Date: December 21, 2006
"I just purchased the 150 filter and it is great! By far the best filter I've had. Great quality, attractive and quiet. I also like that the bottom "arm" that sucks the water up has very fine plastic mesh. I breed guppies and swordtails and this is great because it won't suck up the babies! Overall, great filter. Looks great, sounds great, and keeps the water and fish healthy (and the water crystal clear!)"

Loud, but fixable, love it
Date: November 3, 2009
"OK, so on my 55 I have a pengiun 350. Best filter I have ever owned. Supporting that I had a petco brand 30 filter. I felt it was stupid to be buying 2 different filters all the time, and the petco brand filters clog so easily and limit water flow. Since I loved my 350 so much I decided to get a 200 as the support filter. I plugged it and and from moment one the impeller was loud and grinding. I took it apart several times and tried to do 6 different things to quiet it. Nothing worked. So I took the impeller out of my petco one that I am not using and Whalla. Quiet as could be. The petco impeller is twice the size of the penguin one. I love the filter media and the flow rate of the pengiun filters, but it seems as if the filter itself has gotten cheaper. Still, great filters and will continue to buy. Clear the water up better than any other I have used. Gave it four paws because of the impeller needing switched"

3AM solution
Date: October 26, 2009
"As previously stated, this filter as-is is pretty darn loud. My solution, replace the standard impeller with one from my defunct Whisper. The magnetic barrel is wider, and I'm guessing this was part of the cause for the operating noise. All in all, great product, just be prepared to shell out an extra $5 to buy a thicker impeller!"

Great filter, horrible noise!
Date: October 26, 2009
"I'm writing this review at 2 o'clock in the morning to warn you all that this filter is LOUD. I am really shocked, because I absolutely love Marineland. I switched from a Whisper filter earlier today that kicked the bucket, deciding to upgrade so as to not have that happen again. My water cleared up within half an hour, it was great! The noise was bearable, too. Started off as a dull hum. That hum has now become a roar, and I've disassembled the filter twice now, but can find no problem. Impeller is A-OK, my water level is to the lower portion of the black tank lip. I'm wondering if this is just a straight up defect, and I shouldn't just go back to the *ugh* Tetra brand. So yeah, just a warning to anybody. Great filter, but probably not best in a bedroom tank!"
