There may be a some 'hoop la' surrounding the New and Improved, Marineland Emperor 450 Pro bio-wheel hang-on back filter; I thought that I would give my impression of the filter. ...
I just, installed my Marineland Emperor 450 Pro today, 2-15-2020, replacing the Marineland Emperor 400 that I have been using on my 36 in long x 12 inch wide x 17 inch tall, 30 gallon, long, aquarium for many years.
I removed the Emperor 400's bio wheels' fabric, (loaded with beneficial, bacteria), and the wheels, and cleaned them, (in aquarium water), and installed them into the Emperor 450 Pro instead of using the Emperor 450 Pro's brand new, bio wheels.
I filled the filter with aquarium water before starting it, but I did notice that the flow began immediately after plugging it in, unlike my Marineland Emperor 400 which, whether filled up or partially, filled, would take a few noisy, seconds to begin flowing.
I like the quietness of the filter; there is a very, faint, vibration noise when the lid is closed tightly, but this is hardly noticeable; yet, I do not have the lid closed tightly. I do like the 'flip top' lid very, much. I did not like how well the lid locked its tabs into the slots in the filter, making it a bit difficult to easily, simply, lift the lid from the filter; I used an emery board and filed down the tabs slightly. After the filter had been running for a few hours the filter began to make a 'chattering' sound, I found that slowly, reducing and increasing the flow, using the 'flow regulator', seemed to eliminate the chattering sound, maybe there was a bit of air in the intake system (?).
I do not like the fact that the front, center of the filter very, slightly, (approximately 1/8" to 1/4"), extends further into the aquarium than my Marineland Emperor 400, and will not allow the front of my glass top to fit inside the lip of the aquarium and close completely. The rear of the glass top butts up against the front of the filter, and the plastic strip on the rear of the glass top now, will not extend to the rear lip of the aquarium, leaving about 1/4" open, and the front of the glass top has to sit on top of the aquarium's edge. .. I used my Dremel and a grinding bit and very, carefully, very, patiently, ground out a notch in the center of the rear section of the glass top to allow for the filter, and allow the glass top to fit properly.
It would have been very, convenient if the Bio Wheel Bearings had been of the same design, (fitting in the bearings' slots), as the Emperor 400; I have many, spare bearings for the Emperor 400 on hand. These bearings do get worn and have caused the Bio Wheels to not spin, they do need to be replaced, occasionally.
The Emperor 450 Pro has good, strong flow, creating a fair amount of turbulence in the aquarium. When the 'flow regulator' reduces the flow, at a certain reduction setting, the spray bars stop putting out water. The water then, flowing out of the filter is barely, enough to spin the bio wheels ever so, slightly, and irregularly, and the filter will emit a 'gulping' sound. This 'gulping' sound comes from the spray bars not emitting water and sucking in air, removing the spray bars and blocking the spray bar holes will stop that 'gulping' sound. It appears that the spray bars do not spin the bio wheels, but rather it is the flow coming out of the filter that spins them. I liked the Emperor 400's spray bars much, better with their five outlets across the length of the spray bars, rather than the Emperor 450 Pro's single outlet at the end of its spray bars.
I was not able to use the 'surface skimmer' extension at the top of the inlet tube, or need to use the 'extension' that slides out of the inlet tube, due to the height of my aquarium.
I like the size of the Intake Strainer and the fact that I am able to spin the strainer around and so, I am able to conveniently and easily, clean the debris from the outside of the strainer. .. As another option, I am patiently, awaiting shipment of the Marineland 2-in-1 Bio-Foam Pre-filter that I ordered from Marineland through Amazon. I have a heavy bio load in my aquarium and I like the option of being able to use this pre-filter on the inlet tube instead of the inlet screen. I believe that the pre-filter may extend the life of the Marineland Cut to Fit Bonded Filter Pad or the Marineland Rite Size E filter cartridges. It may also, extend intervals between having to clean the filter itself internally.
So far, I am pleased with my decision to purchase the Marineland 450 Pro. If it is as reliable as my Marineland Emperor 400 has been for its many, years I will be very, satisfied.
