vavoli Posted January 4, 2012 Report Share Posted January 4, 2012 Hello, I have a Eheim filter (unsure of model, but it's a very big external "professional") that is not pushing out as much flow as it was a couple of months ago. I recently gave it a thorough clean out hoping that it was a blockage but it is still quite weak. The output used to blow the fish around but now it's almost a sad dribble. Does anyone have any ideas? Thank you :smln: Quote Link to comment Share on other sites More sharing options...
#!CrunchBang Posted January 4, 2012 Report Share Posted January 4, 2012 did you clean around the impeller? Quote Link to comment Share on other sites More sharing options...
Hamstar99 Posted January 4, 2012 Report Share Posted January 4, 2012 Has it got air locks in the pipes? Quote Link to comment Share on other sites More sharing options...

Snowman Posted January 4, 2012 Report Share Posted January 4, 2012 My money would be on the hoses, you shouldnt have trouble with an eheim for years. Only trouble ive had with them is that you cant lever out the impellor with the ceramic shaft :oops: Quote Link to comment Share on other sites More sharing options...

vavoli Posted January 6, 2012 Author Report Share Posted January 6, 2012 Sorry for late reply on this post everyone! Thanks for the advice. I'll invest in a pipe cleaner brush and haven't been brave enough to pull out the impellor but will give that a go next week when i'm scheduled to do the filter again. I always take the pipes and flush water through them at great speed to get rid of chunks but nothing came out. Media: filter gravel, filter ceramic noodles, eheim sponge and filter wool. No air bubbles in pipes, have checked that one. Yes the filter is great. Tank is still spotless and happy, i just want to get the pressure back up so the water is cycling around properly.

Li@m Posted January 6, 2012 Report Share Posted January 6, 2012 On my aquaone external i can control the flow on each pipe going in and out of the filter, Can you do this on yoir cause its quite easy to forget to re-adjust them. Quote Link to comment Share on other sites More sharing options...
vavoli Posted January 6, 2012 Author Report Share Posted January 6, 2012 Just had a fiddle and it's all where it should be :o/ Will try the impellor cleaning next week Quote Link to comment Share on other sites More sharing options...
blueether Posted January 6, 2012 Report Share Posted January 6, 2012 haven't been brave enough to pull out the impellor but will give that a go next week when i'm scheduled to do the filter again.This sounds like you clean the filter quite regularly. They shouldn't need cleaning often, and then not too much - the wool / sponge maybe once a month - 1/2 the filter gravel / ceramic noodles each 6 months :dunno: I hope you get the flow back up to where you want it Quote Link to comment Share on other sites More sharing options...
vavoli Posted January 8, 2012 Author Report Share Posted January 8, 2012 Hiya I do the filter every 3 weeks ish. But thank you I'm trying to muster some steam to do it today Quote Link to comment Share on other sites More sharing options...
mcmillanm Posted January 9, 2012 Report Share Posted January 9, 2012 I've been having a similar problem with my external aqua 1000 lately too. The pipes looked a bit murky but nothing too serious. I was amazed at how much muck came out though while cleaning and the water flow is now SOO much better. :gigl: I hope it works just as well with yours! :thup: Quote Link to comment Share on other sites More sharing options...
