From the little that I know, these are the most basic water measurements you take to find out your water's quality.
Your pH needs to be around 8.3.
Your nitrites and ammonia should both be at 0 after you're done cycling. They're toxic to fish. What happens when you first start cycling your tank is that the ammonia spikes, then falls, then the nitrites spike and fall. Nitrites and then converted into nitrates, which are not toxic unless they are very high (over 40). In fact, I believe a small amount of them are beneficial. But.. definitely wait for other answers. I've had my tank up for a total of 2 weeks, so what do I know? lol :happy:
