overnight death

possible PH??i have heard that you can actually mix your WC water too much/too long. too much mixing and aerating and it causes precip. changing the PH, Ill try to dig up the link.

 

My tank is only 30 gallons and I know things can change quick... I just don't understand why it happened this time and not any of the other tons of times I have done a water change. I do it the same every time with the same salt and water.

 

I am so sorry to hear about your loss .....it is such a sinking feeling to see that....my crash was due to decreased oxygen but it was because I had insufficient skimming when I started running biopellets.......could something have gotten spilled in it? there has to be something that caused it....

 

Could power surges somehow shock the fig to death? First thing I thought was my heater must have broken but it was still working fine and there was no power outage that reset our clocks or anything over night. I don't see how anything could have spilled in it. There are no shelfs or anything above my tank anything that gets added is from a person pouring it in.

 

Anyone use any spray cleaners nearby?

Floor cleaner?

Use antibacterial soap before sticking hands into tank?

Windex the glass?

 

MY father has been staining our new stairs... i dont know how he could have gotten some in my fish tank though

 

Very sorry for your loss and I feel your pain. That is really sad to here. Yes staining the stairs could have done it. I heard similar fish deaths when someone had their window open and a neighbor was using aerosol spray paint and the fumes got in through the windown.
:-(

 

my friends tank was next door many meters away where some pest control was goin on, and all fish died.........

 

Are the stairs near the tank? when I asked about something getting spilled, I was thinking about kids - sometimes I've heard stories where they "feed the fish" various things trying to help nemo and such .....fumes can be pretty powerful from staining products....

 

you mention your water parameters were in check, when is the last time you tested and what were the results?

+1 on what Corailline said once something goes bad in a nano you have to move fast.

sorry for your loss regardless
