Honestly, for the money... its hard to beat. When looking for a skimmer for my 50g cube I was looking at the nac 3 swc 120 tunze , nac 7 ect.. basically the nac 3 just didnt move enough water for my liking and the nac 7 and swc 160 had too large of a neck for my load. So this fell right in place. And at about $100 shipped it was really hard for me not to try it out.
Not a bk, or atb. But for $100 its a good choice. My lid doesnt fit really well on mine but I can sand it down to get it to fit better. Just havent as its not that deep.
