Cascade® Canister Filter Pumps for Fresh & Saltwater Aquariums - UL Listed

I have a cascade 700 canister in my 40 gallon heavily planted tank and it's a truly wonderful filter. It was easy to set up. It's powerful (all of my plants wave in the currents created by the spray bar and the fish seem to enjoy playing in it). My water is crystal clear and I love that I can put whatever media I want into the filter baskets. Best of all, the filter is really easy to clean: disconnect the hoses, carry the filter to the sink, replace the filter floss, reconnect the hoses, and plug it back in.

Last week one of my shut-off valves started dripping. I e-mailed Penn Plax to ask them where I could buy a new one and they replied to my e-mail within about 2 hours asking for my address and apologizing for the inconvenience. Today a large brown delivery truck arrived with a pair of new filters. I'm overjoyed. This is an awesome company.

I have kept tropical fish for over 30 years. I have tried a lot of equipment over those years, from cheap to expensive. When it comes to filters I have tried cannisters by Eheim, Fluval, Marineland and Penn-Plax. In my opinion, this filter is the best choice. In fact, it is replacing a much praised Eheim 2217. Go on any aquarium forum and you will read a lot of debate about what filter is the best. In the end, Eheim earns the highest praise. Especially the Eheim 22XX series. I bought into the hype and purchased an Eheim 2217 for my 75 gallon aquarium. The Eheim while quiet (silent quiet) quickly lost its ability to create water flow (this is where the Eheim fanatics will talk about "pressure" and "no by-pass" making the Eheim special). The water in my 75 gallon aquarium soon became unacceptable. I decided to look for a supplemental canister filter to support the Eheim 2217 and stumbled upon the Cascade 700.

I thought this filter would simply provide filtering support to the Eheim, but within a week of placing the Cascade in the aquarium, the Eheim's impeller began making noise and the water flow stopped completely. I removed the Eheim determined to repair it, but... the Cascade 700 does a great job keeping the 75 gallon aquarium in tip top shape all by itself! Yes, it is noiser than the Eheim (not nearly enough to be disturbing it's just that Eheim is silent and this filter is barely audible), but it works and it works well. My aquarium has been running solely on the Cascade 700 for 3 months now and it looks fantastic.

If you want to impress the people on tropical fish forums, purchase an Eheim. If you want a reasonably priced filter that out performs the Eheim line in every way, this is the way to go.

I've been using a Penn Plax Cascade 500 for a year in my bowfront 29 gal tank. It's inaudible, a cinch to clean, and it does a great job of filtering the water. And it doesn't leak. I advised my son to get the same filter for his turtle tank but he got a Fluval 105 instead, and it's been nothing but problems. You're supposed to grease the o-ring with special Fluval grease every time you take it apart, and even then it continues to leak. In the end, it's easier to replace the o-ring every time you clean the filter, which is a joke. We're going to trash the Fluval and get another Penn Plax Cascade 500.

This machine is easy to put together, thought the instructions seem a bit overwhelming at first. It had done a great job with my 40 gallon tank and I am using it with for my Turtle and has been very capable at cleaning the water of a usually very messy animal. It is nice and quiet except for the high pressure and flow rate of the output tubing. I merely extend the tubing so that it ends below the water level and the noise of water is considerable reduced. I have only good things to say about this filter after using it for 3 weeks. A solid purchase for sure.
