hey guys im new to the forum, and i own a 50 gallon saltwater tank the tank has been runing for about 2 yrs, i have a wetdry filter, a uv filter, compact lighting, everything is running good, but for some reason over the last couple of weeks or months, alot of algae red and green is forming on the tank very quickly i mean i ahve to clean it maybe every 4 days, i have fiji live rock in the tank, right now i only have 4 fish in there and i noticed there isnt as much snails as i had before maybe due to the starfish eating them? i was wondering if anyone knows what to do?? or can help me in anyway thanks
