Question About Filters

[bllackpython]

So i went over to the parents house for Christmas and was talking to my step-dad about fish. He use to have fish and gave me his old filter saying it's good, etc. I'm still quite new to this hobby so i didn't want to just go ahead and change the filters. Seeing as you guys are so helpful here i hope you don't mind me asking another question.

Here are the details:
My tank is a Fluval Roma 125 and I have Fluval U3 installed.

[It's quite bare atm I'm working on sorting out (Got some bogwood soaking) want to get real plants. Plus that's Christmas wrapping paper in the background which is only a temporary thing!]

So the filter I have been given is Eheim 2215:

I understand it would need a good clean before i use it. Would i need to replace the filter pads?

Also on the box it says 250-350l:

My tank is 125l, is there such a thing as too much filtration?

So overall my question is should I change to this filter or keep with my U3? And if you think i should change is there anything i should do before putting it in my tank?

Thank you in advance!

The only concern with overfiltration is creating more current in the tank than the fish can handle. Some fish require still water, bettas and guppies benefit from that... but others really thrive on fast water movement, like zebra danios, rainbowfish, etc. You have to match your tank to your fish and vice versa.


How long has your tank been set-up? Running the "new" filter alone isn't good unless you move your "old" media to the new filter to bring the beneficial fish over. I don't see a reason not to use the filter, but I also don't see a need to use it either. Maybe this is an excuse to get a 300l tank?

Thanks for the reply!

The tank has been up for about 6 months now. Not sure i'm quite ready for a bigger tank haha.
Well i would have changed if there was any advantages to make my fishies happier.
Seeing as there isn't i think i'll keep to my current one as it's less hassle.

Bigger tanks are actually EASIER than smaller tanks. The water chemistry is more stable...

just keep it as a spare incase your current one stopped working?

Most definitely a good idea...
