You need to check for nitrites after ammonia. If you have no ammonia AND no nitrites with only nitrates showing, then you are good to go with the water change and stocking.
You should really get a nitrite and nitrate test kit. Nitrite spikes are the longest part of the cycle and almost always get to off-the-chart levels. Without a nitrite or nitrate test kit you have no way of knowing whether nitrites are being converted to nitrate or are just accumulating (which, like I said, happens for a very long time, usually making up the bulk of a typical ~1 month cycle).I dont have a way to test nitrites, but I am assuming since the bacteria can quickly convert ammonia, that the nirtrite bacteria is converting to Nitrates. And since this has been going on awhile, I think my cycle is complete. Im gonna do a 90% wc and add fish and see what happens!
