Something wrong with my tank!!! Help!!

what kinda sand do you have in your tank i ask cuz i had the same problem for over 6 months finally found out the person i bought my tank from had bagged sand in the tank and it build up selici (spelling) changed it out for live sand glad i did lost over 400 dollars worth of fish
 
Silica wouldnt have done this. The worst it would have done is caused an algea out break. It has to be move then that. I just went though the same thing. I had somewere between 12-15 fish now done to 5. But I also moved my tank to the new house and ended up not saving enough water so basically it seems like my tank is cycling again like its new. Have you done any major changes to your setup?
 
Changing water will not cause a new cycle..... unless you used chlorinated water and that killed all the bacteria in the live rock.
 
You live alone? Mom's are notorious for cleaning w/o regard to what's around them.. I've heard all sorts of stories of do-gooder mom's and dad's that stick their hands in the tank for any reason w/o remembering to wash their hands off first. All sorts of nonsense can arise that way.

I think the best way we can help you is if you list, in detail, everything about your tank setup. Did you have a boxfish, an unknown cucumber, new coral, etc etc...

I agree plus the big question----did you remove the dead fish?
 
yes everything that died i removed when i find out from comin home from work or from school. i havent done any major changes to my water. everything was good but everything just started to die for no apparent reason. but yea my mom and dad ocassionally comes in my room and clean or even look at the tank but i havent asked if they touched the tank or not. its wierd. i just got home from school yesterday and found out my blasto was dead and it was fine for like a month it just started to lose its color!
 
I dont understand how you could say selica couldnt do this it is the exact same thing that happened to my tank.. my fish went first and then the coarls started suffering just my opinion
 
the only thing that is surviving is my duncan and my frogspawn is infected with brown jelly disease and im tryin to disinfect with lugols solution
 
Something is killing everything...odds are it is in the water. So a couple of large water changes are the only way to get it out. Right now that is the first thing I would do. Any time I have a problem, I do a big water change first then ask question later.
 
i have childs playsand in my tank with no adverse affects. unless the sand might have absorbed something and is slowly leaching it. was the tank new?was it ever used for something else?
 
Whoa! Hold the horses. Are you treating with Iodine straight into the tank? If you are, how much are you putting in? I didn't see anything about testing for iodine in the water.

that's a given swivel----when in doubt the first method of maintenance is to do a water change

you don't know who much those fished decomposed before you got home
 
the tank was up and running for around 4 years and it started to leach out i take it. like i said i tried everything and finally thought to swap out the sand. Are you running carbon at all in this tank? that might help to pull something out atleast I dont know about a water change i mean its only a 12 gallon tank!

Jafish--the smaller the tank the more necessity for weekly water changes and the less margin for error. Three fish dying in a 12 gal tank and sitting there all day----I think that was the problem---he should have done at least 50 per cent of it in a water change

I'm still trying find out how this tank is being filtered and if there is any live rock in there at all.
 
understandable but when you say huge water change there isnt much water to play with im just worried about him loosing some of the organisims and benificial parts of the tank.

50 per cent is huge but not uncalled for esp with three fish dying and left all day and assuming no live rock or little of it.
If it is changed from the top levels of the tank and poured back in over a saucer on the bottom not much of the bacteria etc will be disturbed or removed.
Remember most of the useful bacteria is not in the water column, rather in and around the rock and sand bed and most of the organic laden water rises to the top layers of the tank
