"There are way too many threads with FX5 issues. Leaking, stopping, micro-bubbles and many more, but yet so many people swear by them and recommend them. Fluval have gone downhill just like
Marineland. All they are concerned with is profit and thus their products and customers suffer. I would stay away from both manufacturers"
This is a post made just recently by the system administrator on the FX5. Just wanted to include this for the record. OK I'm done back to the issues at hand just found this and wanted to include it.
I've been lucky enough to not have to get too involved in these arguments as of late, but I guess now is the time.
The FX5 is one of the most highly used and regarded filters on this site. It has great flow and is easy on the pocket book when you need to filter a large tank with little effort. And no, I am not some "Uber Filter Club" member. I have bought 4 or more of these filters and they have all worked flawlessly. I'm sure that there are the occasional issue as with any mass manufactured product. This doesn't mean that they are junk. As stated, there are a variety of reasons why these filters can have issues, many of which are human error. Same could be said for the Rena XP series of filters. Some love them, some hate them. They've been great filters for me, but I have had more of those filters fail than anything else. Doesn't mean I have to instigate arguments about the filters everytime they are mentioned. Maybe instead of arguing, one could take it to task to inform others about issues to keep an eye on.
And since I've taken the task of responding, I'll add this. I find the term "Uber Filter Club" to be designed as a derogatory insult towards those that like and support FX5 filters. Everyone has a right to an opinion and the ability to defend it. Please discontinue use of this term.
The OP has fixed his problem. This topic is done.
