Thanks for jumping in here sammy. Fishkiller is my friend that I got to sign up here and I don't want him getting the wrong information, not that anyone has given any.
Just to give a little extra background:
But, yeah, he had gotten some damsels. You know how nasty damsels can be because LFS' don't always take as good care of them.
Well, the ones he had came in with ich. Unfortunately they started spawning and infected his clown, and coral beauty too.
However, just because he doesn't have a skimmer now, doesn't mean he shouldn't get one.
A skimmer is the best possible method of mechanical filtration for removing excess nutrients, fish waste, and other harmful contaminents from the tank.
In fact, I believe it is more important to skim a smaller tank versus a larger one.
So fishkiller, I say you get some kind of skimmmer asap. That should be your next purchase after getting more LR and everything. It can wait for a while though considering there are no fish in the tank. The main thing now though is that LR. Next time you come over, look at my skimmer cup. You will see all the green, foamy, nastiness. And when that dies down, you will see all the green liquid nastiness in the cup. Just picture that stuff remaining in your tank. The corals, fish (when you get them) and inverts will all be subjected to that. But, if you skim... it takes it out.
In turn:
Better water quality.
Happier fish
Happier corals and inverts.
Thriving tank.
