Hey everybody, this is my first time putting a message for help on this site. This is a great site, been getting alot of info from everybody, thank you. My 12g nano cube deluxe has been running for about a year and hair algae is growing all over the place. Lighting is what came with the tank and there's a white algae blennie, green barred goby, occelarius clownfish and a royal gramma, also a bulb tipped anemonie and a green galaxia. I have the lights on for seven and a half hours a day. Is that maybe too much, and I also try not to overfeed. Any suggestions would be very much appreciated. Thanks alot!
