    You have big problems if your sag is 0.024 it should be 1.025. Buy some SALT

    First thing to ascertain before any action is taken, is that has the SG in fact actually dropped.

    Over what period did the SG drop?

    What happened to cause the SG to drop?

    Answer these and we can help further.

    Bud just a little heads up. If you post multiple questions all over the forum, reefers get confused and are less likely to help. Be patience and you will get loads of good advice. :thumbup:

    It is impossible for the SG to drop overnight if no additional water is added.

    Cannot happen. Well actually it can but your temperature would have to have a huge change.

    Either your 1.024 or 1.017 is incorrect. Or both.

    You say you use Oceanairum water. What is that? And where do you get it from?

    OK I thought you were in Sasolberg. My bad.

    But that water will not change SG overnight. I have not worked out the actual temperature change that will effect that sort of change. But your SG readings are incorrect.

    hahaha mayhem:tt2:

    Ok Sorry guys, this is the situation. My water change was done on saturday, a good 15 litres in my nano 128 litre tank. The salinity was 1.022. It had been lower but with frequent water changes it slowly rose, the water is from 2 oceans aquarium.

    Since that water change with natural salt water on saturday, another test was done today, after my lady noticed that half of the torch coral was gone, dead. (It had 2 cones, one is still looking wonderful, the second was destroyed) The reading was 1.017. It is a Boyu TL 550 so there is no evaporation.

    Could a sudden unexplained drop in salinity cause one cone of the torch coral to die, creating a clean up crew feast?

    This is the torch coral in question, the right side is gone now.

    @sheldar I have checked out some other posts you have made tonight. I am inclined to think you are leading us up the garden path.

    Anyway it is extremely irresponsible to give advice via the bush telegraph. Get your sons lady in contact with me or any reefer and help will surly be given.

    Ok my bad. I thought your dad was leading us up the garden path. My apologies.

    As I have said it is impossible for the SG to drop. Evaporation will cause the SG to increase.

    Touch corals are not a coral to put in young tanks. What you describe is common in young tanks.

    Would a couple of cleaners and peppermints consume all the remains in a few days?

    Thanks for the info, I honestly thought that it was a crab hitch hiker than went rampage. I recently pulled 1 out 3 weeks ago and since then, I haven't had any thing vanish. So I guess that there are no crabs left.

    I doubt it was a crab or other critter. From the euphyllia species the touch is the most difficult yo keep. You need a well established and stable tank to keep them successfully.

    Depending on your filtration. I would just siphon out the dying part into a filter mat to reduce the load on a young filter.

    Recheck the SG and also check for phosphates and nitrates.

    1. The torch was a slight impulse buy, it looked awesome and I was told by a trusted shopkeep that it would be ok in a new tank. Learning the hard way it seems :)

    2. The nitrates was up to 25 because of the dead torch. Clean up crew has done a bang up job I must say. The SG and phosphates will be checked tomorrow, still stuck on the rig.
