    Been very good to me. Did my research and people couldnt tell the difference from the Emperor 400. So i bought this since it’s price tag was way cheaper than the 400. Ive been running this for about 2 months on my 75 gallon tank. I have an Oscar and they’re messy eaters and leave particles in the water from some certain types of foods. The particles dissapear after 20 minutes due to the power filter’s water gallon suction ratio. I completely love how silent it is. You need to fill the tank up to at least the waterfall lips of the filter so you wont hear the water splashing. Good good stuff here.

    Only one drawback… I have a 55 gallon community tank with angels, pleco’s, clown loaches, and cory cats. Some messy fish, but this filter carries the load. My only recommendation is to clean the intake tube with each water change. It gets pretty gunked up, very easily.

    Best filter EVER. Don’t listen to the 1-star crowd. I have had my Penguin 200 with the bio-wheel for about a month now. Before I bought it, I did some research and read the reviews about this particular model. I saw all the bad press people were giving it about it’s “restart problems” and “Bad Connections” etc. etc. and I have to say, the only problem with the P-200 are the short-bus riders who don’t have their water ALL THE WAY UP TO THE BOTTOM OF THE OUTPUT AREA.5*s*t*a*r*s, the bio-wheel is super, it isn’t noisy (you know it’s on, but it doesn’t stop you from reading a book), and my fish have personally told me that they love it. My fish talk to me.
