I have a rather odd question for you and I hope you are able to give me an answer.

I just got my hands on a 63ltr mp eheim aquarium. I also have a Eheim wet/dry 2327 filter. Can I use this filter which takes up to 350ltrs of water per hour on the 63 ltr tank, since I have the filter already, or would it be too powerful for that tank. I plan to plant the tank quite heavily and stock it up to it’s max. My concern is the very powerful flow rate. Can this be done or not? I will eventually buy a 150 ltr tank so for the moment (about 1 yr) i'll have the 63ltr...
 
The gph (gallons per hour) should always be around 8x your tank capacity. That's a good rule to go by, also if you're dealing with messier fish then it's better to have over filtration. So unless you're using some that's upwards of 15-20x the tank capacity you should be ok. It looks like you've got about 16x your tank capacity, I would tone it down a bit. Get the GPH to about 120-140 gph range
 
That's only about a 15 gallon aquarium... You wouldn't want that much power flowing through it. There should be a "flow set" on the filter to let you set it to the GPH that you want. But like the previous comment, you should really only have 100 - 150 max gph flowing around in that size tank, or else it will blow your fish around.
 
I can set the flow rate, since it is a wet/dry, and since it's free I doubt i'll fork out the cash to get a lesser model, if anything soon enough I'll upgrade the tank size...

Thanks for all your help, great site and quick responce!
 
Why is a large filter a bad thing? I have a fluval 304 on a 33 gallon tank (left over from the time I had some big, polluting goldfish). Currently, I have a very small fish load (pink kisser, 3 wag platys and 3 neon tetras).

I have a fluval 204 at home but it's not in the best working condition...

Why is over filtration negative?
 
It really all depends on how many of your fish know how to surf :D

All kidding aside Having that much flow in your tank isn't necessarily bad. Some fish like fast moving water (cichlids for example), some don't (like Angel fish). You can also adjust the flow rate on many filters so that might help.




(Yes, I realize Angel fish are cichlids, but you catch my drift)
 
You guys are missing the point. This is a 15 (US) Gallon aquarium. 350gph is way too much for any freshwater fishin this size aquarium, perhaps saltwater, but thats a different story.

But yes, it really depends on what you have, but it's still too much IMHO
 
Seems I've looked over that, thankyou keith... But still, 350LPH is still quite much for a small tank.
