I followed the instructions in the manual, which it say fill the dome with some tank water then add the chemical to for the changing of the colors. Did I do this wrong or right. Also it started out blue, then turned to green over the weekend, then this morning it was slightly yellow, which mean too much co2, I have the needle valve set at about 60 bubbles per min. I need some help with the settings. The CO2 runs all day while the light is on, then at night it is turned off and the bio wheel is turned on to add some surface movement. I just need some feed back and help. :1zhelp:
