    Hi all

    I did a water change over the weekend 20% for my 120 Litre tank

    Before water change all animals and corals where happy

    After water change --> two dead turbo snails and my Green Star polyps have gone from far extended to unextended for three days , i can see some white parts and some brown on it , is it dead also?

    All my fish are fine in the tank
    Cleaner shrimp and Starfish also seem 100%


    Any advice what may have caused this, really dont want it to happen again

    I quickly tested nitrates and ammonia
    Nitrates -- 0
    Ammonia -- 0.2 (Think it was the two turbo snails that were unnoticed for a day

    Any help much appreciated

    what water did you use to mix the salt? Are you topping up with water without salt as the water evaporates? more info there chief ;)

    Inverts like snails are especially sensitive to sudden changes in PH and salinity. Check those...

    Yes please Tjokkie.

    What is your SG/salinity of your tank? and the same for the water that you mixed up? What was the temp of the replacement water? And your tank? It had to be a huge change in "SOMETHING". One of the parameters of the water was out - definitely....

    Inverts are far more susceptible to differences in water parameters, than fish.

    I will check Ph in a few minutes and see
    I didnt mix the salt and water i bought the water from a petshop where i also get my water (Pre mixed)
    I top up with RO water only

    Any advice on the coral :)?

    Ok Ph -->8.4
    Alk --> Normal

    Hydrometer --> 1.028 , this was much lower before water change im sure

    Eish, sorry man, try do 10-12% rather, 20% is very large water change for such a small tank volume, and if you have to do one so big, rather make sure of all your parameters are close to what they are in the tank.

    actually, needs to siphon out some water, max 1% (.5 will be better), then fill that back up with RO. Add RO water in first chamber, and add slowly. Test per day until back at 1.025

    There you go Tjokkie! ;)

    I think that the water you mixed to do the water change with, had too high SG/Salinity.

    And do as Wes says - remove some of that tank water (you can keep it if you want to - just dilute it as well with RO water), and replace it slowly with RO water..... Take a few hours to do this, to bring your tank's salinity down.

    Then, 100's.... Unfortunate about the inverts that you already lost! ;)

    When you referring to your cforal, I assume you are referring to your green star polyps?

    They should survive. What you see is most likely as a result of them being burnt by the increased salt level.

    Highly recommend you invest in a ATC refractometer and pH check water parameters of bought water.

    I wrote an article which should hopefully be in the printed press soon, explaining a bit about the water we use.

    Green star polyps, Not Xenia. They usually are tough as nails, actually a pest IMHO. They should pull through. They just got burnt a bit.
