I have noticed my tank getting a little cloudy over the last few days and when I went to go check everything in the back out i noticed my skimmer is not working at all. My question is this: I know that everyone gets the tunze skimmer, but I also see people getting another kind. Also do you think I should just add a sump on the bottom and put the filter to that? Thanks for all your advice, I better be getting to this tank soon, but thank god I have a plate coral and nothing else in there yet.
