I'm in the process of setting up a small 20 gallon reef. I'm gonna have a tetratec filter on it, and 2 55W PC lights illuminating it. I have a seaclone skimmer that I raided for the powerhead a while ago, and am considering getting another powerhead for it. I would like to put a skimmer on the tank, but is it worth fixing it, or should i do without, or go for something else, like a bakpak, or prism?

thanks,
