Filter Media, Sponges And Wool

[barlow1984]

I've had my tank for 3 months and am wondering how often the sponges and the wool they sit on should be changed? I have 2 trays in my filter, in addition they have ceramic noodles underneath.
 
I read that the noodles should be replaced annually and that I should alternate the replacement of the sponges and wool, but how often?

Sponges - Never, Unless they fall to bits. But they last AGES, So don't look at replacing those anytime soon.
 
As for wool, I would change it every few weeks. You can buy block wool for your filter that costs around 14 quid and lasts around a year or more.

Thanks Techen, would something like this be the right thing to buy: http/www.ebay.co.uk/itm/5m-AQUARIUM-POND-FILTER-MEDIA-WOOL-FLOSS-ROLL-5-8mm-/260728515110?pt=UK_Pet_Supplies_Fish&hash=item3cb4a16a26&_uhb=1
 
Feeling bad for not changing it in 3 months now!

Haha yes, I bought that stuff and you get ALOT of it. I mean a lot of it, It works great and lasts forever. Well worth getting yourself some, they sell thicker and thinner stuff so it's entirely up to yourself which you buy.
 
I mean wool is good for picking up lots of dust and fine things, So changing it often will keep your tank water very clean. It's good

Yeah it's gone very cloudy after my filter clean and water change today so I think it's needed!

Yep, Just switch over every few weeks and you'll be sorted.

If you choose to change out the noodles then only change a handful at a time, many don't bother changing these either but there is a strong argument to say they should be. Micropores getting blocked etc.
