  1. Default Rena XP3 set up questions?

    0 Not allowed!
    I just bought a Rena XP3 for my 75 community tank. I thought it would come complete with everything to set it up, but I guess not. As far as how to set up the baskets.....It came with several filter pads for the upper & lower basket, and a Carbon bag.

    there is room to put something else in the baskets. What about the microbiological media? How much should I get to put in? Is one type better than another? Can you overfill it with bio media?

    Any other advice would be helpful.

    Canisters provide lots of versatility as far as what type of media you want to utilize, particularly if the canister is used to supplement (or is supplemented by) a HOB filter.

    I recommend to save the 'Bio Chem Zorb' (the 'carbon bag' which also contains ammonia removing media, if I'm not mistaken) for an emergency and replace it with bio-media. Most of my XP3's are predominently filled with biologic media (bio-chem stars, ceramic noodles, left over Seachem Matrix rocks, etc). You can't "overfill" the canister with biological media.

    You could also configure them to perform a mechanical filtration role (using pads in each basket as opposed to the top and bottom one, etc). There's a trade off though (increased mechanical filtration but lower flow rate).

    Any Bio media any better than the others? I was just going to go to petco or petsmart and get whatever was the cheapest.

    Anything that is high-porous with a large surface area would be ideal. I'm not familar with what type of biological filtration media is available at those two places, though.

    Just bought the Fluval bio media. Only 1 500g package. I'll probably add the Rena stars as well next time I take the filter apart.
