    Hello all,
    I have a question, I have a Tetra Whisper 30-60 HOB filter on a 29 gallon tank. Would it help filtration if I were to add Bio-Media to it and how would I do it? I would most likely use lava rock of ceramic cylinders, I got those ideas from the king of DIY.

    Many Thanks- personman

    Not sure about lava rock, but you could add the bioballs into your filter is they fit, but with whispers the spongy thing, and your floss on filter pads will contain bacteria. If you are having issues w/ your nitrigen cycle is it possible you are overstocked or need to add some more bacteria? (TSS SafeStart)
