So i was on vacation for the past week. I had someone taking care of the tank in the sense of turning off the lights, turning them on, feeding, and doing the weekly water change. Everything looks good just a lot of algae growth...like a lot, Just wondering how you guys would go about this to try to clean it out/prevent it. I was thinking a sand sifting goby may help as its a sand bed, but i'd like some more experienced input before i add anything
