Aquarium Systems - Millennium Power Filters


My opinion: skip the Millennium filter line, there are better filters available. I had an Emperor and Penguin for a 55 gal tank and did not like the performance of the Penguin. Local store recommended Millennium because it was about $10 cheaper and did not have priming problem of the Emperor. The advantages of the Millennium 3000 are: 1. few pump priming problems; 2. adjustable water flow; 3. less obvious lift tubes. The disadvantages are: 1. original filter media which worked well has been replaced with standard filter. Doesn't fit the same and reduces water flow unnecessarily; 2. lift tubes break at the connector and replacements are not available. Bottom line: filter won't work with broken connectors; 3. Smoke tint is too light and algae grow at top of lift tube and because of the water flow adjuster it is hard to clean with brushes. My recommendation: either stick with Emperor line or go to something like a canister filter system.

I don't like the Millennium. I have a Millennium 2000 on my 75 liter tank with cichlids. The tank is cloudy most of the time. There is not enough charcoal in cartridge to prevent the water from smelling. It's a nice concept, but needs to be redesigned to make it more versatile and efficient.

I have a Millennium 3000 and I have to say that its really great! I put it in my 60 gallon tank and works so great that I put it up against a fluval 304 in the same tank and it out performed the 304. I gave the 304 a good two week run and it could never get the water as clear as my M-3000.

After I had my Penguin Mini filter die in my 40 liter tank, an employee at a local fish store recommended this model to me, as it was new at the time. Anyway, it's been going for about two years now with no problems. It was an excellent purchase then and I totally recommend it to others. The gimmicky BioGrid actually functions and provides good biological filtration (I took it out for a week to see if it made a difference and ammonia levels jumped). It's a bit noisy, but I sleep in the same room with it running, so it's not much of a problem. This plagues most filters of this type, but when the power shuts off, you must reprime it quickly, or the motor will get hot and possibly burn out. Also it's not as popular as other filters such as the Penguin or Emperor models, so filter cartriges might be a little hard to find, so check on the internet if you have to. Overall, I am very satisfied with this product and recommend it.

I have been using a single Millennium 3000 filter in my 200 L tank, no problems. As for cleaning the water flow adjuster, my small brush and some vinigar works great. The the lift tubes will crack if not handled with care, so be careful. Overall, I would recommend this filter to everyone. You can purchase repalcement carbon filters on line for about $11.00 for a pack of four.

I have the Millenuim 3000, and I love it! It's so quiet! I can't find the replacement cartridges for it though, so for a lot cheaper, I just make my own! I buy activated carbon (the black stuff) for $5.99 and a big bag of filter floss for $1.99 and it lasts me a LONG time. I also like the fact that its clear...its easier to see inside the filter if you need too, but if you have a lot of algae its not pretty to look at. The pros out-weigh the cons by far!

I have been using Millennium 2000's and 3000's in some of my tanks. The replaceable filter cartridge has charcoal inside it and is thrown away. I found some replacement filters made by Ginger that did not use charcoal and cost less and my tanks were fine. Then, to cut costs further, I tried an experiment. I went to a fabric store and bought some batting. It is a light weight type of material that I thought would be similar to the mesh on the replacement filter cartridges. The material is not as stiff, but it works. I kept the plastic part of my Millennium filter and tore off the mesh material and threw out the carbon. Next I cut a piece of batting and put it in place of the old mesh with just enough width to bring it around the sides of the plastic filter frame. Next I insert it into the slot in the filter. Well, it worked. The small roll of batting cost me about US$6.00. Each filter replacement costs me only about US$0.07 each. Very inexpensive when compared to the price of buying filters. Now I can afford to change filters as often as I like without incurring much expense. I have done the same with Whisper filters also. This eliminates the charcoal, but I haven't missed it. My fish have been doing fine. Just a note: I have only had freshwater fish tanks. I don't know if it would work as well with a marine tank.

I've had two Millennium 1000 power filters for about 12 years. After getting tired of replacing the inserts with new ones, I began using just the old frames, and filling them with carbon and wrapping them with batting from a fabric store. Then I got tired of THAT, and just cut down a huge Aquaclear sponge to fit into that space and that's all I've used now for the last..... 10 years. Gets clogged up? Just squeeze and rinse. I don't miss the carbon, as my tanks smell like garden soil without it.
