Hmmmm.......interesting posts thusfar..........
I have no idea why the one gentleman's hoses get clogged unless he's running a heavily planted tank. I've been dabbling in this hobby since the '70's, and have never had nor seen clogged hoses.
Eheim filters, at least the Classic line, are remarkable in their horrible design, difficult operation, and high pricing. I owned a couple different models many years back when they were relatively new. They were difficult to prime, difficult to keep running, and a huge mess to clean. However, their reputation is very good, both for quality and customer service. I will never be a sucker again for overpriced items, not only designer brand aquaria products, but clothing, cars, tools etc.
Fluval makes good filters that run efficiently and quietly. The design is sound, and even though it has some bypass, it's not the space shuttle. No filter is, nor should it be. Filters are designed to mimic nature. A babbling brook is nature's way of cleaning water, and a filter just concentrates all the media present in miles of babbling brooks. Fluvals are good filters at reasonable prices.
I've no personal experience with Rena filters, but there has been a lot of talk on several forums about leaks developing around the power cord entry port on the motorhead. It would seem most of the failures occur at around a year of service give or take a few months. From what I've read, there are enough occurences of this failure to be noteworthy. There are also a lot of complaints about noisy operation.
The Via Aqua filters seem to get a thumbs up across the board, albeit with a few minor complaints of water bypass.
The Jebao (NOTE: JEBAO is a completely different company from JEBO)filters are pretty highly regarded throughout Oceana and Asia as well as Europe. They're marketed under a plethora of brand names, and I believe Via Aqua is one. They're not too prominent here in the US.
The Jebo filters which include Odyssea, Newport, Lifetech and some other brands are supposed to be direct knockoffs of Eheim. This may or may not be true. Jebo is a conglomerate company made up of Chinese, Canadian and yes, German partners. Some of the Jebo Canister (most are not seen in the US) filter components have "made in Germany" on them. The CSF4 (828, 838) is a Chinese product of unknown origin of design. Some or all of the components may or may not be of Chinese manufacture. Possibly some German manufacture as well, but there are rumors that the design of the CSF4 is strictly German. The Jebo filter is not as quiet as the Fluval or some other Asian designed filters, but IT IS quiet nonetheless. It is a decibel or two above silent. The media baskest aren't as sturdy as their Eheim counterparts, but they don't need to be. They only need to hold the media, not hold up a building. The filter moves a lot of water. Some would like to argue over the actual amount of gph
in comparison to this brand or that, but all the filters in this class move approximately the same amount of water, give or take a few gallons. The Jebo is efficient, quiet, cavernous, easy to setup and maintain. Parts are available through limited sources at the time of this writing, but I'm sure more parts dealers will spring up soon enough with the growing popularity. The filters don't leak, are easy to prime and do what they're supposed to. All this at a very inexpensive price. In fact, they're cheaper than many HOB
filters, powerheads, and internals.
There are a lot of loyalists, particularly those who favor Eheim. Could it be they're justifying paying too much? The Jebo is "all that", and you can believe it or not. As someone who has experience with many brands, I've made up my mind not to succumb to brand name Euphoria. The Jebo offers the most bang for the buck. In fact, it offers triple or quadruple the bang for the buck.
I might add, I have no professional affiliation with any manufacturer, importer, designer or retailer. My opinion is my own.
