I think its a pretty decent skimmer. I could go buy a new one, but im happy with it pretty much, just would rather have drier skimmate than mainly water. Maybe I'll sell it and get a new skimmer when I upgrade to a big tank, but right now its the biggest skimmer I can possibly fit under my tank. There is roughly 1/2 clearance on top of it. Other than the wet skimmate and the frequent floodings (which i fixed with an overflow tube in my reservoir bottle) its been a good skimmer.
What kind of skimmer would you recommend upgrading to with a big tank? price isnt really a huge concern with me, I like to get just the best right away and not worry about it. (to an extent, nothing too outrageous). But out of curiosity what do you guys use on your 125g+ tanks? Still interested in knowing exactly what air pump works well with a CSS 125g to make nice bubbles...
