Aqueon 06081 QuietFlow 20 Power Filter, 125GPH

Aqueon QuietFlow Power Filters and cartridges were designed with the fish and the aquarist in mind. Our patented designs include unique features to enhance water quality and clarity, increase oxygen levels and lessen noise. Aqueon QuietFlow Power Filters feature four stages of filtration-mechanical, chemical, biological and wet/dry-for the cleanest, clearest, healthiest water. Higher flow rates ensure higher dissolved oxygen content for healthier, more active fish. The internal pump design helps dampen noise, eliminates leaks and starts up automatically after cleaning or power interruptions.

Product Features

Higher Flow Rates

Aqueon filters have higher flow rates than the competition to ensure proper turnover for cleaner water and higher dissolved oxygen content, making fish healthier and more active.

Superior Biological Filtration

The patented biological grid has a large surface area to support more of the beneficial bacteria that eliminates ammonia and nitrates. A second wet/dry grid provides further biological filtration and oxygenation as the water returns to the aquarium.

Internal Pump Design

Since the filter pump is submersed in the aquarium, there is no need for priming at setup or when restarting the filter after cleaning or power interruptions. An internal pump also allows for virtually silent operation, continuous flow raters, less chance for leaks, and a much thinner profile.

Four Stage Advanced Filtration System

Stage 1: Dense floss removes particles and debris.

Stage 2: Activated carbon removes toxins, odors and discoloration.

Stage 3: Patented Bio-Holster removes toxic ammonia and nitrites.

Stage 4: Diffuser grid removes additional toxins while adding oxygen for more active fish. It also reduces splashing makes the return exceptionally quiet.

    Works great if you make your own filter inserts 0

    Amazing Value! I inherited one of these filters used from a friend, and I have been using it nonstop ever since. I run some more expensive filters on my other tanks, such as the Fluval 306 canister filter, Marineland Penguin series, Tetra Whisper and Penn-Plax Cascade. I can honestly say that this Aqueon filter is one of the best filters I have, and if I ever have to replace one of my other HOB filters, there is a good chance I would get one of the Aqueon filters to do so.Let us first make clear that any HOB filter will require a minor investment in filter cartridges. I have run this particular filter on a tank with gouramis, and currently on a tank with neon tetras and albino corys. How do I make my cartridges last so long? Well, I have one of these attached to the intake: This prevents too much debris from being sucked into the filter while increasing the biological filtration, the most important stage in filtration, as any good aquariust knows. These Fluval sponges fit perfectly and in no way inhibit the flow. They have saved me a lot of money on cartridges, and when they get dirty, I just rinse them in some aquarium water and put them back on. My flower shrimp also love to eat particles of food from the sponge!As for being quiet, mine runs silently. I never hear this filter running. If you get one that makes a lot of noise, please see about getting a replacement as I have never had this problem, and as I said, this is a pre-owned filter.As for being reliable, because of its design, this filter starts right up after a power outage or water change. No priming for this filter! This is the main reason that I would replace one of my other HOB filters with one of these. The Marineland filters require priming, the Tetra Whisper filters are meant to be self-priming, but can be somewhat unreliable. My Aqueon filter has always started up again after being turned off. This is great peace of mind, especially when I am away from home for a few days.As for being effective, this filter holds its own against its competitors. True, it is not an Aquaclear, but it is just as good as any filter using a standard carbon cartridge. Its bio-filtration may not be the best, but this only becomes an issue when you have to replace the cartridge, and if you are using a sponge pre-filter as I recommend above, you should not have a problem with your tank cycling after a cartridge change.Now, let me make a few points:1. This particular filter should NOT be used for goldfish. This model is designed for ten gallons or less, and a ten gallon tank is not appropriate for a goldfish. Besides, goldies create so much waste that they require at least TWICE the recommended filtration. For example, on my 75 gallon goldfish tank, I run a canister recommended for 70 gallons, a HOB recommended for 70 gallons, and 2 Hydro Sponge filters recommended for 40 gallons each. Over-filtration? Maybe, but goldies don’t mind the current, and it keeps my water clean. In addition, even the smallest goldfish will grow too large for a ten gallon tank, and if the fish itself doesn’t grow, its organs will, and it will eventually die a painful death. I did once put a small common goldfish into a ten gallon hospital tank temporarily, but I did so with plenty of filtration. This Aqueon QuietFlow 10 is not enough for any kind of goldfish in any tank whatsoever.2. This filter should NOT, in my opinion, be used for any Betta. It doesn’t create a super-strong current, but it is still too strong for a fish who prefers still water. I have found that a Hydro Sponge filter powered by an air pump is all you need to filter a tank for one Betta. I have a male crowntail Betta in a ten gallon tank, and I do just this. I also have a female Betta in a five gallon tank, and I use a Whisper internal filter set on its lowest setting, and this seems to work as well. The Aqueon filter is NOT appropriate for a Betta.3. If you overload your tank, you need more filtration, and you will have to change your cartridge more. Research and learn what kind and how many fish can go into a ten gallon tank, and don’t exceed this amount. It’s a bad idea for everyone involved, especially the fish.In conclusion, this filter is economical, silent, reliable, and well-designed. It suffers only from a somewhat inferior system for bio-filtration which can easily be remedied by the addition of an inexpensive sponge pre-filter. This would be a great filter for beginners because of its simple design, and also a great choice for those of us with more experience who are on a budget or for whom it is impractical to run a canister filter.UPDATE:Hey, everybody! I was browsing through some filters looking to add additional filtration to a 40 gallon…
