Frag Tank Filtration

[brian313313]

I have put a few paly frags in a 10g tank that I have. I don't have any fish or anything else. Since I'm not feeding them, is any filtration necessary? I can't think of any reason since nothing is going in but just wanted to get other opinions. I did put a small circulation pump in there.

throw a HOB filter on there to run some carbon or other media. fish are important to a frag tank IMO you need fish waste so corals have some thing to eat. corals love fish waste 8)
