Product Description

Quiet, efficient and reliable Aqua Clear 20 pumps 100 gph. Recommended for aquariums up to 20 gallons. Aqua Clear stands alone as the only aquarium power filter that offers the integrated filtration of the CycleGuard Insert System. Aqua Clear combines the largest volume of efficient filter media in individual inserts with the powerful water flows from the free floating impeller. Alternate replacement of the CycleGuard inserts ensures continuous biological removal of organic toxins can be achieved. The waterfall style output from the Aqua Clear filter agitates the surface of the water while creating beneficial currents throughout the entire volume of the aquarium. Both the surface agitation and the rotational currents bring more water molecules to the surface, in physical contact with the atmosphere, enabling them to release carbon dioxide and replenish oxygen more efficiently. In addition, the constantly moving water currents do not allow dead spots to occur in the aquarium, eliminating the possibility of thermal layering. Water input per hour is regulated by adjusting the patented flow adjustment mechanism, tailoring the flow rate to the aquarium's requirements. When the flow adjustment reduces input, the water returned to the aquarium is still equal to input, but the top grid in the filter basket circulates purified water back into the motor chamber so that the pump filters 100 gallons per hour even when adjusted to siphon less. Water may be filtered more than once without reducing the actual flow rate of the pump unit. The Aqua Clear 20 actively draws dirty aquarium water through the integrated siphon/strainer assembly into the pump impeller chamber. The flow diverter directs the powerful water current from the impeller chamber under the filter basket. The water is forced to move through the provided filter media and then returned purified to the aquarium. Aqua Clear Power Filters are designed to fully exploit the benefits of removing aquarium wastes both mechani

not really low noise - Judith Hoppe, Oct 17, 2009

This filter comes with three types of media to filter the water, loose carbon a nylon bag, ceramic disks, and a block of foam. It seemed to do a pretty good job of filtering the water (some people remove the carbon and buy an extra bag of ceramic disks), but I did not like the trickle waterfall sounds it makes. It has a design flaw on the waterfall that causes bubbles intermittently. There are no curved surfaces on the spout -- only sharp angles. Some of these are shipped with motors that are a little noisy and I was told that there is a break in period of sorts. My motor had a gravelly sound that did not diminish significantly over nine days of use.

I ended up returning my filter to the local fish store where I bought it. Right now I only use a Koralia Nano powerhead on my 10 gallon marine tank because it's very quiet; freshwater tanks require a filter however. You can get by with no filter on a marine tank if you have sufficient live rock or live sand.

This is a great, cheap to run filter! - J. Burke, Sep 28, 2008

Unlike other filters that force you to spend money on new filters pads every two weeks, spending a lot on money you didn't think you would have to, this filter does not require replacement filter pads. Instead, it has a block of foam that is used to trap the dirt in the water. Every two weeks, simple clean the foam in water by squeezing it a few times! Just do it in your water changing bucket with de-chlorinated water.

You can change the carbon filter whenever you choose to. In fact, it is not needed all that much. I have run my tanks without carbon for a month at a time, no big deal. If the water starts to look yellow or brown, it is time to change it and put in some fresh carbon.

Works Like a Dream! - C M LaFleur, May 12, 2007

My daughter has a small aquarium (approx. 5 gallons),and we purchased a smaller filter, top of the line name brand, when we purchased the tank (as recommended). We had many problems; did not circulate well and left residue on the top of the water as if it were stagnant. Our angelfish kept dieing. I researched filters and decided to give this one a try as it said it did not allow "stagnant" water to happen since it was constantly circulating and flowing back into the tank from rim level. It is wonderful!! It sits comfortably on the rim of the tank in the cut out area. The water flows rather like a gentle waterfall. Our angelfish are doing well and I am very happy with the appearance and quality of the water in the small tank at all times. I have never seen any slimy areas and definitely have not seen the top look like pond water!! Our new angels love the filter and were hanging out by it and getting pushed around a little by the flow of the water...they seemed to be enjoying the activity. This is a very reasonably priced small filter that actually does the job it states it does....I highly recommend it to anyone.
