I am supposed to be aming for 300Mv. I need help in trying to recitfy this problem.... any suggestions, besides the obvious, water change, ozone, better skimming.:)

    You need to attach an oziniser to the Mv controller. I run my Mv at 400

    There is no quick fix method, rather look at your stock. Are they happy, if they are then dont worry. My advice here is dont get too hung up on ORP readings.

    don't read too much in the level, but u r on a very low side. 400 is ideal. i raised my ORP but 80 by adding a ozonizer and by another 50 but upgrading my skimmer. there are some many factors to consider in ORP that one cannot just say do this or that.

    Some basics:
    How old is your meter ? new ones can take up to 2 weeks before it gives an accurate reading. Did u calibrate the probe after 2 weeks of installation?
