Would it be better to use live rock in the back on an AIO tank instead of bio filters like seachem bio matrix ??

I agree 100% here. I don't understand what those matrix type products and bricks do that a rock won't do. And, I think some people believe that some of the blocks they've tried leached metals into the tank. I'd go with the live rock personally.

  • Quite a bit, but an automatic feeder can change my answer

    Votes: 6 14.3%

  • It depends on whether my nutrient export can handle it

    Votes: 6 14.3%

  • It depends on how badly I want the fish

    Votes: 10 23.8%

  • Not much. I’m willing to adjust my routine

    Votes: 9 21.4%

  • Not at all. Feeding demands don’t limit my stocking choices

    Votes: 8 19.0%

  • I usually learn about the demanding feeding schedule after buying the fish!

    Votes: 2 4.8%

  • I haven’t really considered this before
