OK so i have a 55 gallon goldfish tank at my house and a 95 gallon oscar tank at my office..
to cut a long story short im in the process of buying another company and expanding my business so im going to be out of town quite a bit..

So 3 days ago i did my regular 50% weekly change on the goldfish tank.. well within 2hrs of the water change the goldies where on the bottom hardly moving and heavy breathing.. i did a quick water test and all the levels were great .. nothing different in water quality than normal... well i let it go for a few hrs while i went to do groceries. came back and 3 of the 5 had died... so i was confused as to why so i did another 30% and put new filters in the tank and double dosed the prime... well now comes the morning and another had died and the last guy is barely hanging on.. did a bunch of research more water test and i cant find anything wrong.. well as i type this the last guy is really on his last leg i dont think he will make it through the night....

so my question is how can i test to see if there is any disease in the water that came in via the water change...

i would like to drain the tank clean everything down re fill it add my canister filter plus my penguin 350 and put the oscars in so my wife can feed and keep an eye on them while im out of town...

any help in this matter would be great im out of ideas

You're sure the equipment used for the water change wasn't used for something else that could have contaminated your WC equipment?

If water being added is drastically different from tank water can cause osmotic shock. Is your water supply from town or tank?

disease in the water doesn't happen that quickly

What are your numbers and test the water coming directly from the tap water on here as well. Need to start ruling out possibilities.


I added a sponge filter to my 65 and it caused a min cycle to take place. Ammonia spiked the end of the first week. Please post your numbers.,
65 gallon
2 yellow tail aceis
1 male cobue peacock
3 female cobue peacocks
1 male blood dragon
2 Synodontis lucipinnis

5.5 Gallon
Delta tail betta

Tank water
nitrate 15-20ppm
nitrite 0ppm
hardness is 75
alkalinity 0
ph 7.2



tap water
nitrate 0ppm
nitrite 0ppm
hardness 75
alkalinity 0
ph 6.8


im using the 5 in 1 test kit as my api master is at my office and for got to bring home so i use this one as a back up... seems to be exact same as my api when i do a back to back test to confirm if things are spiking...

Did the last goldfish make it through the night? I find it really crazy for almost an entire tank to be wiped out in under 24 hours, following a water change; it makes me strongly suspect contamination or a big swing in water parameters. You said it took 2-5 hours for the first three to pass, one followed the next morning, and 3 days later the third guy is just holding on? Just want to make sure I understand correctly.

Thinking out loud......
  • Weekly 50% water changes wouldn't likely be causation for osmotic shock. The fish would've been adequately conditioned to handle the newly introduced minerals.
  • There is surety the equipment used to perform the water change wasn't contaminated since the last time it was used.

The only other things I can think of are:
1. The temperature of the new water was significantly different than the tank water being removed - causing some sort of temperature related shock similar to what happens to a human when they are suddenly introduced to drastically different environmental temperatures.
2. There is/was a poisonous contaminate in the water that you've been unable to identify due to not having the necessary water testing equipment.

Other than the above....I'm currently at a loss.
