Hi have you done any water tests, plus have you been moving any rocks or sand about lately as if you have you have most likely disturbed some Sulpher Dioxide which will kill all life. Its no good saying all the fish are dead as we can not see them so we need some more info before we can help. HTH Twiggy

Post more info on your tank-size, sump? pumps? skimmer? water params etc

get some water done quick so you can find out if there anything in the water causing it,then you might be able to save what fish you have left.derek

hi my tank is 200 litre with 30kg live rock a and deep sandbed it all started when my power head fell off the glass and blew my dsb all over i have done some test just now here they are
amonia = 0
nitrite = 0
nitrate = 35
salinity 1.026
temp = 26
ph = 8.3
there the only tests i have
i am running a canister filter with rowaphos and carbon and a mc300 deltec skimmer not pulling mmuch out

[Tangman]

Hi you have the DSB in the tank, that is maybe the cause when the p/h disturbed the sand it will have released toxins into the tank so killing the fish. HTH Twiggy:D

i have left my tank now for 2hours with the power heads facing the surface my clown fish has perk up abit and other fish seem ok but the clown has poppy out eyes wich are cloudy any thoughts

[Tangman]

Hi it sounds like the clown has maybe been affected by the spike somehow, just keep an eye on her and see how she fares. Also maybe do some good quality water changes to help dilute what is in there. Twiggy:D:D

Just a thought but what powerheads do you have? It could have been oxygen depletion (clowns eyes?)- not enough surface movement, that killed the fish then when you've moved the rock, as Tangman said, released 'baddies' into the water. For a tank your size you should have at least 2000 litres/hour movement preferably more than double that.
