    need help... i suspected my salinity pen was wrong when i tested some lfs water with it... so i recalibrated it with solution and retested with refractometer... and my tank was sitting at 1.0328 specific gravity!!!!!!!! :eek:

    luckily my fish are all alright!!!

    how many days should i look at bringing it back to normal?
    is there a way to work out how much water to replace with RO per day?

    Add RO bit by bit over about two hours and test continually in between... And stop doing top ups with salt water... :lol: You'll be fine, don't stress... :thumbup:

    initially just with calibration fluid... but now i used tank water of known salinity (double tested) and then caompared to two different refractometers readings... its spot on now. has anyone heard of someones tank reaching a higher salinity?

    I always calibrate my refracto with RO water and zero it, then do my tests, so maybe try that going fwd

    I would imagine so. Just add RO as advised above and take saltwater out SLOWLY. You dont want to shock them further.

    First off, don't panic :p It's not too bad, you may lose one or two corals, but your fish should be fine.

    How many litres is your entire system?

    And any idea how your salinity managed to get to this level?

    300L system... my sailinty was PERFECT (accoding to an incorrectly calibrated salinity pen) ie: i made the salinity high accidently cause the pen was showing a lower reading

    As Dean said dont panic, dropping salinity is not as much of a shock to the system as raising it, so it can be done relativly quickly as described above.

    Yes, as Alan said, dropping salinity is not such a big shock... Even less than a day... Just do it bit by bit and keep testing... ;)

    by having high salinity your corals will definatly salk. Depending on how long the salinity is high for, it will cause the coral to bleach and eventually die.

    Agreed, but as you do have corals in the tank, I would rather take it a bit slower, dropping the salinity over 2-3 days (with a fish-only system you could safely do it in a few hours...).
