Okay, I've Tested And My Guppies Are Still Dying.....

OTT - over the top. i've had guppies a while now and 9 small guppies guppies in a 10 gallon is fine and regular water changes nullifies the results from any test as the water is regularly being replaced. you should be asking what the condition of the fish is, what they look like and how they are behaving..

I agree it's over the top for regularly scheduled water changes, but you're talking about a tank that has fish that are dying. There don't see to be any physical signs that the user is aware of at this point, so while I wouldn't change that much water daily on a normal basis, it does help eliminate the bioload question.
