About The Product

With its attractive cobalt blue color and sleek design, the Penn Plax Cascade 1000 canister only adds to the ocean-like charm of your aquarium tank. This is more than just a good-looking filter, with its stellar features that make it easy to install, start and maintain, giving you a tank full of clean, pure water that is continuously being filtered.

In addition, placement is no worry for this canister, thanks to its independent directional 360-degree rotating valve taps. 


There’s more to this product than just this one feature, and here’s a sneak peek into what else there’s to love about the Penn Plax Cascade 1000 canister filter:

Enhanced Flow Control

The Penn Plax Cascade 1000 canister filter has more than one feature that allows you to control the flow of clean water to your aquarium tank, starting with the flow-rate control valves, which allow you to determine and set the flow of water as per the needs of your aquarium.

This feature gets even better thanks to the swimming pool-style hose clamps which make it easier to maintain the flow you’ve set without having to come back and check the filter frequently for consistent water flow. This means that you never have to worry about water flowing too quickly into your tank and upsetting the gentle, tranquil environment that some fish may need to thrive.

3-Stage Filtration System

The Penn Plax Cascade 1000 canister filter has three trays designed to hold a wide range of filtration media, allowing you to customize your filter with practically any combination of media including bio-floss, bio-sponges, activated carbon and others to meet the needs of your aquarium tank, irrespective of its size, kind of fish and salinity of water.

A word of advice - if you find the media trays to be slightly smaller than other brands, you could try packing some floss on the sides of one of the trays to increase the quality of mechanical filtration - this shouldn’t be too much of a problem, since the very idea of canister filters is to be able to add more of the media that you think your aquarium needs the most.

Users have experimented with everything from using two trays of floss, one of charcoal and a hang-on biological filter, to simply using one tray for each kind of media, getting effective filtration for their aquarium tanks.

Ideally, as long as you manage to zero down on a combination of filter media that give you adequate mechanical, chemical and biological filtration and eliminate all kinds of organic, chemical and particulate matter, you should be able to use the Penn Plax Cascade 1000 to keep your tank water sparkling clean!

Self-Priming Filter

The Penn Plax Cascade 1000 canister filter is designed with a self-priming pump, which makes it super easy to restart the filter after a power interruption, or if it has been disconnected for cleaning or replacement.

A word of caution - there seem to be mixed reviews about the quality of the self-priming - while most users were either able to start the filter almost immediately, a few struggled to get the priming right, mostly because of an error in following the installation manual.

In any case, this can be easily avoided if you give the manual a thorough read, and make sure all the tubes and hoses are connected the right way. In addition, the Penn Plax Cascade 1000 has an easy push-down button which eliminates the need for manual siphoning of water to get the pump working, making it a hassle-free pumping experience.

Easy Installation And Maintenance

This the probably the one feature that stands out more than the others - the Penn Plax Cascade 1000 canister filter is practically a plug-and-play setup. It comes neatly packaged with all the components in place, and users have been pleasantly surprised to open the box and find a piece of equipment that is made with sturdy plastic, making it last longer than some of the flimsier models in the market.

Every single valve, hose, tube is made from high-quality material, giving your canister filter a long life and giving you some great value for your money. Once installed, the sturdy rubber mounted rubber base keeps the Penn Plax Cascade 1000 standing strong, without the risk of tipping over.

What Users Are Saying

Users of the Penn-Plax Cascade 1000 canister filter are exceptionally happy with the product, and seem to love its powerful but super-quiet filtration, with nearly every review mentioning that this filter gives their aquarium tank crystal clear water without fail.

For the price it comes for, this canister filter has also managed to woo its users with the quality of the components of this filter like clasps, valves and latches, putting them at par with other high-quality but expensive brands in the market.

Most importantly, customers are happy with the fact that the media trays in the Penn-Plax Cascade 1000 are big, and can be customized with media of their choice, making this a great product for aquariums of different kinds.

What To Lookout For

Some users of the Penn-Plax Cascade 1000 complained that the self-priming pump can be an issue, requiring the pump to be primed manually instead. In a few cases, however, users realized this was a result of not having followed manual instructions correctly. In any case, even the users who had to return their filter because of poor priming were happy to receive better-performing replacements in a short time, and are happy with the new product.

The one thing that Penn Plax does differently is that it offers a three-year warranty on your filter, as opposed to the lifetime limited warranty offered by other brands. But then again, with a product that is as sturdy, you won’t have to worry about major replacements for a long, long time.

Final Verdict

For the price it comes for, the Penn Plax Cascade 1000, available for sale on Amazon for less than $75, is definitely a high-quality canister filter that packs in some pretty great features.

You should be willing to spend time setting this up by following instructions perfectly, but it starts to filter your tank water to make it crystal clear, it’ll be worth every minute spent.

After all, it’s about keeping your fish healthy and happy, and there’s little else that beats the joy of a tank full of colorful, healthy fish darting from one corner to another, is there?
