water change and amonia

[marlinmero]

well i had filled up my 130gallon and it sprung a little leak. so i put the water into a 55gallon and the rest stayin the 130 " it stopped leaking after i took some water out" it has sat for about a week while being filterd and i was thinkin of useing that water to do a water change in my up and running 75. i tested the water and the amonia is at .5. so should i not use it to do my water change?
