There is no single "best" skimmer. Each type has its advantages and disadvantages.
Euroreef-simple design, excellent quality, low power consumption, quiet, very good performance. But: proprietary pump.
Myreef Creations-low price, excellent quality, very good performance, upgradeable, custom sizes available, good customer service. But: require large pumps to work properly.
AquaC new EV series-use relatively small pumps, great customer service, performance supposed to be comparable to similar Beckett models, lots of features. But: so-so build quality, kinda pricey.
Lifereef-excellent build quality, near-flawless design, CVC feature, very good performance, etc. But: pricey, made in small quantities.
