no offense to you carey. i just had a terrible experience with the remoras, and aqua-c.
a bad microbubble issue, lack of skimmate (i used it for 6 months and it never got any better) and the annoying slurping sound that sounded like the suction tool at the dentists office. it was so bad we had to put it on a timer so that we could sleep.
this was a 30 gallon cube and the water coming out of it was yellow. there was no reason why the collection cup shouldn't have been full.
about the microbubble issue, aqua-c told me i needed to buy the surface skimmer box. i did, but all that did was take up a large amount of space and the bubbles continued. then they told me they were going to send me some special bubble diffusing material. a couple weeks later i posted my experience on a forum that they must have been monitoring, and 2 days after that i received an envelope in the mail with no words- just a 2 x 2 piece of nylon window screen in it. that didn't work either.
let's face it, 90% (or more) of the skimmer's efficiency is in the pump. how much faith do you have in a skimmer that utilizes a maxijet 1200?
i don't have any experience with the EV series stuff, but i say stay away from the remora and urchin (the same skimmer with a piece of acrylic glued on the bottom to act as a stand).
