Well let me correct that the xray tetra is not pregnant she's just going to lay eggs then the fertilization happens, felt compelled to correct myself. Well I decided to test my ph, nitrate, nitrite, ammonia levels since I just built the nitrate filter, like I said its rather unnecessary. Ph is around 7.4ish, ammonia 0 ppm, nitrite 0ppm, and my nitrate is at a whopping 2 ppm lol, so I'll see in six weeks if it drops to 0, don't think I have much to complain about with 2ppm and I'm saying 2 just b/c i thought the 0ppm was a little dark.
