I am starting a new aquarium and am doing it with the fishless cycle. its a 10g tank. I add 1 tablespoon and waited an hour before testing. When I did test it, from the kit, i got that it had about 1ppm. So then I added 2 more tablespoons since 1 seemed to get me about 1ppm and that would at least increase it up to 3ppm if not a little more.

While I was doing that, I did not throw away the tested water. When i was going to dump it, i saw that it was darker, meaning it was at a higher ppm. I looked and it was at about 4ppm.

So now that i have about 3 times the dose I needed, should I just let it be as it is now or do a water change? If i should do a water change, how much should I change?
