I need something to remove Comet from a friend's betta fish tank. It was cleaned by one of her workers and killed her goldfish immediately after they were put back into the tank. This friend thinks I am able to make all things right. I need help.
There is so much residue in the tank. I have soaked and emptied the tank over 50 times in the week that I have been working on it. Comet still comes to the top and floats, then settles again. I've tried letting the water run for 2 hours and there is still Comet coming to the top.
This friend is developmentally disabled and needs to keep her betta fish. It brings her much joy in her world where she has little.
If you are having issues with cleansers in the tanks you can follow these instructions.
Fish store approved scrubbing pads
Pour vinegar and salt in the bottom of the tank. Use the scrubbing pad approved for fish tanks to scrub the tank. You dont need to worry about the salt hurting your tank.
Rinse the tank with cold water. Continue rinsing out the tank until you remove the salt from the tank.
Pour vinegar and water in the tank. This should remove the rest of the comment residue from your tank.
Sorry I have been so long in my update reply IT WORKED! Salt & vinegar solution finally removed the comet garbage from the tank. Betta DAISY is doing wonderfully. Told my friend to not even let anyone feed Daisy. One worker tried and she called her momma to come (lives 2 hours away) to fire the worker.
I think even a little residue will kill the fish. I would try to get a new tank cheaply or even free. Check out Freecycle, Craigslist and garage sales.
If you have cleaned that many times I would get a new tank and throw that one out.Get one second hand.
