    Tank crash

    Hello all,
    i'm new here in the forum

    i've been running 2 tanks for about 10 yrs now (190 gallons & 120 gallons) my larger tank crashed about 3 weeks ago due to salinity beeing too low, i took for granted that all parameters were ok since the tank had been running for such a long time, water changes (15%) done every 2 weeks but sadly i lost everything although 2 cleaner wrasses made it though. My Purple tang,Blue Hypo, Yellow tangs had been in there for 9 yrs. i was devastated...you really get attached to these guys

    the tank had been running without a skimmer for about 3 yrs, the same live rocks (about 75lb) in the tank since the beginning. a massive water change (60%) was done about 2 weeks ago, water testing done....PH 8.3 salinity 1.25 ammonia 0 nitrates 0 Calcium 490

    i bought 2 Azure Damsels last saturday and found them dead the next day, so something is wrong....the parameters all seem ok

    any input would be appreciated

    Eric

    wow.. sad to hear about that.
    something must still be wrong.
    how low did the salinity get ?
    you sure its not something else that died.. like a cuke ? those little nukes are potent !

    run a big pile of carbon in there for a few days.
    also check for stray electricity.. that can cause metal leaching and could have nuked your tank as well... also may have contributed to the salinity change.

    moving.. so temporarily out of SW :b8:
    planning next tank, possibly 60x30x20 on 2x plasma.

    The salinity was as low as 1.010 when i noticed, the good thing is that its been steady for the last 2 weeks ranging between .24-25

    carbon? i've never used it before but i should give it a try

    thanks

    I hope you mean 1.025 and not 1.25....if so that is a real problem as it's way too high

    Definitely run a good cycle of carbon in it for a week or two. There must be some contaminants in the water that may have built up over time. Especially with not having a skimmer. Then do a few good water changes. Also, next time you add fish, or any specimens for that matter, check the salinity of the water they're in to compare to your tank for when you do an acclimation. It'll give you a much better idea of what they have to deal with for adjusting.
