Cascade® Internal Submersible Filters for Aquariums - UL Listed

The Cascade 300 inline filter is a good cheap filter for a five or 10 gallon tank that requires a slow to medium current (I use it in 5gal betta tanks) but I would not recommend it in anything bigger as any bio-load over 'light' would overwhelm it.

It has a bio-sponge section and a "Disposable Carbon filter Cartridge" that they want you to buy in packs. I pried open the cartridge it came with to find low grade carbon pellets so I replaced them with Marineland Black Diamond Premium and it works even better now.

I use two Cascade 600 filters in my 55 gallon aquatic Xenopus (African Clawed Frog) tank. As they like to hang at the surface of the water, mate, and eat without getting blown around by a high current, they are happy with the fact that the flow rate is low because I can turn the outlet away from the center of the tank and into the back tank wall. Because they like to excrete that which they consume in large amounts, I am happy that their tank is kept clean between water changes. For larger amphibian tanks, these filters are quite effective AND low in price. More effective in a larger tank than Duetto internal filters. I have Duetto filters in smaller 10-20 gallon tanks for amphibians and find that the Cascade filters are better for larger tanks. You can use the nozzle shown on the box picture or you can use a bar that is included with the filter. They are big, bulky filters that take up space in the tank, but this is the downside of filtration that has low currents. I can not testify as to longevity of the item, but I have been willing to risk the purchase as for the time being we are all very happy. Buy if you want good filtration with a low flow rate at a good price.

I have a red eared slider turtle and his home is a 55 gallon tank. He makes quite a mess in his home and I have gone through at least 4-5 different filters in the 2+ years that I have had him. I've tried the external filters that sound like a constant waterfall only to have it short out. So then I decided to look at submersible filters and went through about 2 of those before I found this. At first I was frustrated because the water started to turn green and it was as though it wasn't working. Miraculously one morning I woke up and the water was crystal clear and has been since then. It's quiet and Homer LOVES to float in front of the water being pushed out. He puts his little head in his shell and let's the water just shoot over top of his shell.

To sum it up it's powerful, quiet and Homer loves the water coming out of the filter. I would absolutely recommend this!!!!!!

I've been using it within the frame of a week now and so far it's doing great. It's more than powerful enough to clear out my 55 gallon tank. I'm going to have to buy a longer air-hose for it so I can put it at the bottom of my tank, but that is cheap and easy to do. Other than that it seems to be the best water pump that I've ever used.

I got this filter for my 10 gallon Amazon River species tank. To start off with, I think Penn-Plax (maker of cascade products) really deserves more recognition. Their stuff has been compared to higher end brands like Fluval and Aquaclear. Like the Aquaclear you can put what ever media you want inside the compartment. You can hook the nozzle up to the provided airline tube (does not need air pump) so it can draw in air and spray out bubbles. Another option is to use the spray bar that comes with it. Since it draws the water straight through the media as a canister filter would, it is A LOT more efficient, allowing it to have a lower GPH. I also like that the pump comes AFTER the media, making sand and other abrasive particles less likely to damage the impeller. It can be fully submerged, and oriented sideways and still operate. You can also attach a tube to it allowing it to be used as a filter pump in a vivarium. It has an adjustable flow, which is a really useful feature. I really like this product and would recommend it to someone on a tighter budget. If you are searching for a filter for your first tank and can't afford a tetra, Aquaclear, and other higher end filters, I would really recommend this, in fact, I would still recommend this even if your not on a tight budget. If you are setting up your first tank I pray it goes well and remember to cycle!!!
