i bought the euro reef cs8 3 i do a lot of research and the true is that a lot of : aqua ev skimmer , euro reef , and even mrc post a lot of probelm and they are the brand name skimmer and most popular. more then that a lot of ppl give very good feedback to asm skimmer ( a lot of member keep 2 skimmer ) and you can see that they decide to buy the second one as asm and they give again very good feedback to this skimmer.more then that you will be surprise that the big jebo skimmer have a very good feedback to and bottom line it's a big different ,honest i already buy my skimmer but it's cost $600 if i could to return the wheel back i would take the chance and buy first the big jebo one about $100. i suggest to you to read a lot on mrc member club , euro reef member club and the aqua skimmer member club to it's big headache they are real brand name and i was confuse to.
