What filter media are you currently using and what are you trying to replace and why?

The biomedia shouldn't ever need to be replaced.

I always used any Ceramics I could get, rather then the Rena Stars. They don't even give you enough to fill the filter, and packs of them are priced like they were made of gold.

I like the aqua clear bio max! They last a long time.A lot longer than those rena stars do! I couldn't beleive that they completely disappeared in only a few months.
The biomax is a little cheaper and last for much longer!

The best bio media I ever used is eheim substrate pro.It looks like cocoa puffs and can really be packed in there and still get good flow through.For the mech filtration basket I use the sponge material they come with..I do not use any chem filt in any of my tanks.Proper water management elimininates the need for that in normal circumstances.

let's see. To do it on the the really cheap, I have heard of people using those nylon scrubby balls for dish pans as biomedia, and pillow stuffing for floss. Personally, i use floss and the biomedia my fluvals came with, which seems to work well.

The surface area makes them poor choices for a canister filter, especially one with only one basket.

The xp-2 has 2 baskets.

For the XP2 I recommend using the 4 sponges (course and fine-pored which come with the canister) in the first basket. In the second basket use micron filter pad (100-micron), then load the basket with bio-media, the lastly, use a 50-micron filter pad). Configured this way you can achieve very effective mechanical and biological filtration.

Can you elaborate on the disappearing media?

I've had the Rena stars in my XP-3 for over a year and they lookthe same size as brand new.
