So for X-Mas my Boyfriend Bought me a 55g tank off Craigs list. The lights were burnt out and there was many scratches, but he did get a good price, even for the stand it came with. It came with about 10 juvenile Guppie fry, and one Medium sized Pleco, which i wasnt to happy about. but he was freaking out cause he had them in a bowl, and didnt know what to do, so i got my present early. I setup the tank and used all the same stuff, including the gravel which was still wet and in a bucket. I changed the filter pads in the over the back whisper. And the carbons on the undergravel filter. Its been setup a month now, no ammonia ever nor nitrate, but i did put live plants in there. My Question is, has the tank allready been Cycled, or am i just still waiting? And I want to get some Angel fish, the PH is 7.6 and i hear Angels like 6.5, should i try to change this? Thanks for anyone that can help.
