    urgent help,
    Over the last few days my tank has taken a total disaster,not sure how or why the ammonia spiked but with such bad effect my tank inmates were badly affected,with my angels being the first to go.

    ammonia was in the red zone in the Sera test kits,ph was 8.7. and 0.09 nitrites.

    what i did was two 25% wc over two days,dosed stability and amgaurd into the tank as instructed.

    also tried lowering the ph which should help to nuetralize the ammonia if ph is lowered to about 7.

    what else can i do?sailfin tang has black spots all over,foxface showin signs of red streaking
    all still swimmin around but not eating.

    850litre tank

    foxface
    sailfin
    bluethroat trigger pair

    All of your parm is haywire, I would do more water changes as in NOW..
    Your Ph is too High too. Leave out all the additives and start doing huge water changes. Stuff is dying in your tank, hence the ammonia spike as well as the nitrites going up. Do you have a chiller, if so, run it wet for the next couple of days

    I would also set up a small container/tank and move the fish over to the temporary tank

    If I put you inside a smoke filled room, and take you out into another clean air room.... basically the same ;)

    noted,but just to check even after a full DT water change,should i still remove them?
    Its a hellavu thing to catch them,have to remove most the LR(thought me messing in the tank will add more stress),but will do it if it will help

    You set up this tank in the beginning of November. I see you mentioned that you are not going the DSB route any more but rather use Fauna Marin or equivalent. What are your main filtration then at the moment?

    Your system built up a lethal dose of ammonia in 2 months. Something in your filtration is missing or wrong.

    yes ,moved evrytin over from my 1.2 to the 2m,with all my existing LR that never left water or circulation at all as i moved to the place next door.
    Using fauna marin ultra bak,and ultra bio,aswell as stability(initial transfer) .

    no dsb in sump but nice 5cm sandbed of aragonite in tank.
    Ammonia was monitored weekly and never showed any signs aswell as nitrates being 0.05 consistently.

    within 10 days the ammonia skyrocketed-no idea as to why

    all dead fish was accounted for and removed besides a springeri damsel.


    after wc completed,had to remove the sailfin:(

    Sorry to hear maj , here is what I THINK. Your filtration is not up to scratch , especially if you have triggers (they are messy feeders and as with all preds produces a lot of waste) . As I work with industrial wastewater one of the things we came across in high protien wastes is they also produce a lot ammonia)

    I think your bacteria was "coping" up to a stage, but as soon as the first casualty appeared the culture justed crashed. I would hazard a guess that the high ph was the cause. Fish can handle elevated ph but not for prolonged periods , it causes damage to gills , outer membranes etc. Also as you rightly mentioned...increases ammonia levels exponentially

    As per seank, water changes would be best, I personally wouldnt do the whole volume in one go , maybe 50 % today & 50 % tomorrow ?

    Also get a decent bacterial product to create bacterial diversity (@Henk Hugo)

    Also a 5 cm in DT DSB will not create both aerobic and anearobic zones , thus you are missing on a part of the nitrogen cycle...

    Good luck bud !

    Good luck !!

    could possibly be the high ph that caused the first fish to go,didnt check that as often as the ammonia levels

    Thing is i knew the bacteria population wasn up to scratch,or efficient enuff but with the matured 105kg of LR and the bac dosing i hoped it wouldv coped but yah,its the only other explanation other than a pesticide gettin into the tank.

    i did 250litre water change daily since friday,so the entire tank volume water has been replaced,thought that would help.
    hoped the waterchanges wouldv correct the ph,but didn thus tried to lower it but didnt help as i thought.


    im so despondent now,feel like packing it all up and replacing hole in wall with a fireplace:(
    il check params in next hour or so.

    wasnt hoping for the sand bed in the dt to do much,thus i dosed fauna marin and stability for various strains and hoped LR wouldv coped

    Damn Maj, sorry to hear. Like Sean suggested, maybe set up a small hospital tank to hold what fish are left. There you can treat them and also do smaller but effective water changes while you get your main system back in order. It will take time, but this way you can manage it better with less stress on the LS and also on you.
