Aquarium Advice Newbie
Hi everybody,
New here. Did I buy a decent filter? I just got a Fluval 305 for my 40 gallon tank with sand substrate. I had trouble with some HOB filters eating impellers and shafts from a little sand getting sucked up on occasion. A friend gave me his old Fluval 204 to play with. It was used on a similar tank with sand for about 6 years. There is some detectable wear on the shaft, but it runs good and is still fairly quiet. My conclusion was that this style filter is tolerant of occasional sand. I'm running 2 Aquaclear 50's right now and they eat impeller shafts every few months even though the pickup is a good foot off the bottom. I also get some Malaysian trumpet snail babies in there on occasion and I think they are as bad as sand. They also don't always restart after a power failure once they get a little worn and dirty.
I started reading a bit more after ordering and I stumbled on a board that appears to hate these filters for leaking. I've got many years of experience with oring seals so when my filter arrived I looked it over closely. I was surprised to find the main sealing surface quite scratched probably from the molding process. Also there were many sharp points to be felt along the seal surface. They felt sharp enough that they could damage the oring over time. So I smoothed the surface with 600 grit wet sand paper following up with buffing to get it shiny again. I'm now confident this seal will not be leaking as long as I pay attention during service.
Other than being disappointed with the QC, I think this will be a good filter. Many years ago I had a Fluval 202. It was a great filter but a real pain to service in the tight location I used it. To move on from that hassle, I went with HOB 10 years ago when I set this tank up.
So anyway, that’s my story. I am just looking for comments on the Fluval 305 and anybody's experiences with leaks. Also interested in experiences with sand getting in filters as well as MT snails getting into things.
I found a small basin to place under the filter and in my pile of junk I found a water leak alarm. I'm pretty confident the main oring will not leak. I haven't quite figured out what keeps the primer pump from leaking, but I don't see that anyone has had problems with that area. Thanks for any comments.
