Lofties Posted November 8, 2015 Report Share Posted November 8, 2015 Hi All, I have a 4ft tank with an old Jabao external filter which runs a bit rough, even stops for 5 seconds sometimes and then restarts! I'm thinking an fx5 would be good, or is it a bit too much? Any thoughts? Cheers. Link to comment Share on other sites More sharing options...
yellows Posted November 8, 2015 Report Share Posted November 8, 2015 What size 4 ft, what fish you putting in it, how often do you feed them I'd say a fx5 would be ok Link to comment Share on other sites More sharing options...
Nini Posted November 8, 2015 Report Share Posted November 8, 2015 I was under the impression that there was no such thing as a filter being "too much", as long as the flow isn't too hard/fast for the fish (don't blast them across the tank without their consent).

ex0h Posted November 8, 2015 Report Share Posted November 8, 2015 Not at all.. I had an FX5 on my 6x2x2 and still had to use a wave maker to get things moving around. The Fluval FX5/6 are awesome filters. Would recommend for 4ft+ tanks any day of the week. Link to comment Share on other sites More sharing options...
Wogboy Posted November 8, 2015 Report Share Posted November 8, 2015 Waste of money though, what size 4 foot, an fx5 is overkill for anything but a 4x2x2, if you are thinking of upgrading go for it though. A 406, is more than enough for a 4x18x18 Link to comment Share on other sites More sharing options...
none Posted November 8, 2015 Report Share Posted November 8, 2015 I run one on a 36 x 18 x 18 marine tank and it's brilliant. Have run them on 48 x 18 x 18's too. No worries. Link to comment Share on other sites More sharing options...
trk18 Posted November 8, 2015 Report Share Posted November 8, 2015 Over rather than under if you can ! Fx5 x 4ft = clean & mostly problem free Link to comment Share on other sites More sharing options...
Lofties Posted November 13, 2015 Author Report Share Posted November 13, 2015 No worries guys, thanks for your input. It's 4x2x2 and usually only has a few striped dollars and some clown loaches. It's mainly used as a spare tank to grow out peacock bass. I'll add an fx5 for sure. Link to comment Share on other sites More sharing options...
