I used to but the ocean is diverse so I figure why shouldn't my tank be plus the only thing that bugs me is the worms but in all honesty they eat every little speck of food the the fish or coral doesn't get one thing I can say is I have never had a phosphate issue from over feeding lol I have my reef keepers stand by set to 30 mins just so that when it kicks back on there's nothing flowing down the drain to rot But they creep me out so I'd like to get a handle on it before its a worm farm . I guess I always looked at it like why kill the good stuff that's the only hitch hiker I have had so far so maybe I'm lucky
