I have yet one more question about the 55-Gallon, which I had in my last thread 'Tank Water Issue'.
What if I take some of the water from the tank and put it into a bin
take out all of the fish and add them to the bin
And just drain the rest of the tank down to the bottom and start with new water? I'd use some water that has already been cycled of course, such as water from the 60-Gallon I have.
I do the same thing with the 60-Gallon every now and again, but only if I'm trying to move the tank or clean the tank really well.
My mother only worries that because she has had the Oscar in the tank all his life (He has never been moved from the tank at all) and the condition of the water that he is already in may stress him out too much and possibly kill him. She only worries about him, lol, none of the others.
So, I need some opinions with this from the people of MFK. I know it would be a risk, but it is a bit of a risk that I think she is willing to take to get the tank a little better than it is now.

If you think this would work, how would I catch a 12" Oscar? lol, I don't have a net large enough, and neither does she, but I had the idea of using a garbage bag to catch him in. Would that work?

this may sound too easy, but go to the LFS and buy a big net, no?
 
That won't help and will only stress the fish unnecessarily. There's no such thing as "cycled water" only a cycled filter. You need to test your water to have a clear picture of what's going on in your tank.

Your initial problem was cloudy water after you had changed to brand new filter pads, followed by fish deaths and trouble breathing. Most likely, this was caused by a bacterial bloom due to a disruption of the cycle in your tank, followed by a buildup of ammonia and nitrite. You've posted two threads but still haven't tested your water.

I only have a Saltwater Test Kit at the moment... probably wouldn't work for freshwater?

The water was cloudy before the new filter pads, and the fish were having trouble breathing before the new filter pads also.
