Hi Alfred, I have a diatom filter, a vortex XL model. It works very well--the water is sparkling clean, and it has seemed to help knock down a bout of ich as well, in one instance. However, it is such a royal pain to set up, that in two years I think I've only used it maybe five times. It's a hassle to prime it. It has to have everything just right in terms of hoses and the filter perched on a chair with phone books and connections and finicky positioning and you reaching to hold the other end of it in place. It's -very- loud, and with it having to run all night to do a good job on my 125, I cringe at what my apartment-building neighbors must hear from the motor noise. I have to close my door to sleep through it, and it scares the cat. Whenever I get an inkling to use it, I peer at its coil of hoses in the dark cabinet and think of better things to do with my time. It's a good backup plan for green water or ich or exceptionally thorough tank cleanings. But a tremendous pain. Good to have used, but not worth using. Other brands may be better experiences. Good luck! -Darcey H -----Original Message----- From: owner-gsas-member@thekrib.com [mailto:owner-gsas-member@thekrib.com] On Behalf Of carrera206 Sent: Monday, June 21, 2004 7:14 PM To: gsas-member@thekrib.com Subject: Diatom Filters Does anyone have any experience using diatom filters? ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe gsas-member" in the body of the message.
