Fikter Pump Losing Power?

[nez2768]

hi all,
everything has settled down well in my tank and thank you all for the help!! have noticed recently though that my Juwel filter pump is not sirculating the water as powerfully as it used to. I have the tank around 8 months and only chnage the poly filter sponge once every week or 2 and change carbon sponge every 6-8 weeks. I recently washed both green nitrate and blue course sponges in aquarian water (every 3 months) and it helped a little but seem to be back to less power again.
Can anyone advise me what the best thing to do is eg: should i change my present blue course sponge to a new one or use a 2nd green nitrate sponge in place of the carbon sponge and if so do i need to squeeze some of the good bacteria form the present older green sponge to either blue (course) or green (nitrate) sponges?
many thanks

Get rid of the carbon sponge, you don't need it. You don't need to change any of the other sponges unless they start to fall apart, just squeeze them out in tank water every few weeks. I had an internal-filtered Juwel Lido for seven years and only once changed a sponge.

As to your lack of flow it's probably the polyfilter. Is it slimy when you change it? Mine always were. My Saturday routine was to take the polyfilter and clean it, then put a new polyfilter in the filter box, place the old, cleaned filter on the top. On the following Tuesday or Wednesday I would reach in, take out the used polyfilter (and throw it away) leaving a pristine one in place. So the the following Saturday the incumbent filter was cleaned and placed on top of a new one and so on.

Basically, I was changing my polyfilter twice a week. I had no issues with flow, ever.


Don't forget, much of the brown crap you see in your coarse and fine filters is the actual bacteria you need to do the job so unless it starts to block the filter up, leave it alone.

I forgot to add...

...buy your polyfilter material in bulk and cut it to size then you could change it every day if you wanted and it would still be cheaper than buying it in cute boxes.

Might be worth checking the impeller and impeller cavity, they could well be caked in "slime." A clean with tank dampened cotton buds should do the trick.
