57m on a single tank would just be so short too; air goes quick at that depth, and the longer you stay down the longer you have to take getting up.

  it was definitely not the plan. I remember being hooked on the wall and seeing my bubbles descending behind me. That dive felt more like mountain climbing than diving.

    Some walls have vicious down currents, but if you just swim away from the wall a few meters the current will decline and you can establish positive buoyancy.

      You're right, but I wasn't willing to take that risk. One of the divers in my group was already in a mild state of panic and I didn't want to chance them letting go of the wall and descending another 10m. I had a plan to deal with the current, but oxygen toxicity is another thing entirely.

        Oxygen toxicity isn't really a factor at that depth; you'd run out of air on a single tank before experiencing any toxicity symptoms. The immediate concerns would be narcosis and hypercapnia.
