    Howsit Guys. I am posting on behalf of my father in law.

    Last night when I was tank sitting I found his longest living Threadfin dead!
    I took a photo of the condition of the rocks and substrate:

    As well as some medication he has:

    I am going to get the water tested today and will post the results as soon as I get them.

    Tank Details:
    FOWLR
    DT: 700L
    Sump: 300L - Live Rock, DSB
    Reef Octo Skimmer
    2400L/H return pump
    1 x power head
    1 x Resun internal filter

    This tank has had bad algae problems for a while now and would really like to help sort it out with some expert advice from the MASA crowd! ;)

    All help greatly appreciated!

    Will post further pics tonight of entire setup.

    add an air stone to raise dissolved oxygen in the meantime.
    just 1 fish?

    Fish are gasping for air and constantly hanging around the return pipe and powerhead.
    They scrape themselves on the rocks and substrate. Also noticed whitespot on a few.

    Will Cuprasin help at all?

    no medication yet, start dosing Am Gaurd, sounds like ammonia or nitrite, also add a pure bacteria source, tank temp to 24deg, will help with oxygen. test for ammonia and nitrite

    I was recently advised to limit airflow in the DT due to a few fish with Pop-eye.
    The return pipe sits close to the powerhead and blows air around the tank.
    Can I add an airstone to the sump?

    So far it is just one fish. The others are looking very sickly! I never saw 3 of of the Wrasse that are usually so active in the tank, but am not sure if they were buried or not.

    with so much algae i suspect high nitrates and phosphates levels. get this tested ASAP. check the filtration system and lean if necessary (filters, sponges, ceramic rings etc). when was the last water change done?
    check all the parameters carefully but my money is on high nitrates and phosphates.

    grasping for air is a key indicator of ammonia poisoning, nitrates of 160ppm are not bad for fish etc, it is also not toxic

    high Ammonia and nitrite restrict the bloods ability to absorb oxygen etc.

    the key here is removing ammonia, and resulting nitrite...
    use seachem stability and seachem prime

    whats the total water volume of your system? what skimmer do you run? and do you have any means for removing nitrates and phosphates?

    if the problem is ammonia like @dallasg suggested i would do a 50% water change. or because your system is so large and that might be very hard/costly/difficult i would say as much as you can afford. do it slowly and if possible make sure that the temperature of the watter you add in is 25 degrees and the salinity is the same as the one in your tank. once done with that you can very slowly over the course of few days try and bring the salinity lower
