Hello! So, I've been doing my first fishless cycle. So far, so good. I'm finishing my second week and I think I'm getting there. Today my readings were Ammonia 0, Nitrites 0,25 and Nitrates 0,50 (yesterday's Nitrites leves were 0.50 and Nitrates 0,25)). I've been cycling with Stability and fish food. Today I finally received the pure ammonia that I ordered online, and as I had 0 ppm for two consecutive days, I added some drops to my 10 G fish tank. Now, I have the following questions : A) Should I do some water change at this point? And B) I'm confused about the PH reading (see pic attached ). Is that 7.6 or I'm getting it wrong?? Thanks in advance!
