First disaster since starting up 5 months ago happened today. I came home from work and noticed a very strong hydrogen sulphide smell (rotten eggs). I thought tha this could only be my Aqua Medic Denitrifier, so while having a look at the equipment to see what the porblem was I noticed a kink in the return pipe back to the tank, to which I straigtned it out.
Five minutes later I just happened to glance at the tank and noticed the flagfin angel (juvenile) lying on the bottom. I rushed to the tank to find the Midas Blenny going blue and dive head first into the CC. This was then follwed by the clown sinking to the bottom. Panic set in, and I rushed to get some new water.
Realising I only had about 10% of the tank made up, I rushed to the store cupboard to get the salt ready to make up some more...shock horror, the Instant Ocean box was empty!.
Like a man possesed I drove to the LFS
to get some more salt, only to get stuck behind some old lady in the queue who couldn't remember what she came for.
Dashed back home and made up 40% water change and did emergency transfusion. Unfortunately too late for the flagfin and the blenny, but my Yellow Tang, clown and yellow headed sleeper goby seems to be recovering. Fortunately all the inverts were OK (so far) so only lost 2 fish.
I was never convinced that the denitrifier was doing anything good for my tank in the first place, so that got taken out straight away.
When I took the top off it my wife nearly had to rush me to hospital with toxic posioning as the H2S smell almost knocked me over!!.
I suppose the moral is, always make sure you have enough salt in the house to cover a disaster, and never believe whatever miracle the manufacturer says it can do.
