my rays have been acting funny for a lil bit now, i thought it was something out of my hands, my parameters are normal as they ever were! i did notice a slight ph jump but from 6.0 to 6.5, but i thought it was from me water changing and not adding enough proper ph 6.5 in the tank. low and behold under some move sand i see a penny!! my son must have threw it in or something. i'm going to do a large water change and finger rake all my sand but is there any other advice that would be beneficial?
