I am a lurker and almost never post, but I happen to have BOTH of this skimmers working right now. My AquaC Remora is an old version, I bought it in 1999. It does a very good job and continually skims whatever color skimmate I want. It is noisy and this is an issue because my tank is in my bedroom. It also clogs up about every 6 months and needs a muriatic acid bath to get it working again. This is a big pain because I have to tear the whole thing down and invert it in a bucket of dilute acid deep enough to submerse the water intake. I understand that the newer skimmers allow you to dismantle the intake for cleaning...haven't seen them.
On the other hand I have the tunze skimmer on a 10-gal. nano that was set up this summer to house 2 clowns. I am a BIG fan of Tunze skimmers and have an old 3110 that is currently not in use. I am very impressed with its performance. It takes a while to settle in, but you can make VERY fine adjustments to the air intake to dial exactly what color skimmate you like. It is the quietest skimmer I have never heard! When you clean the cup the air intake is flushed with water to diminish clogging. When you replace the cup after cleaning, it begins skimming almost immediately again. Of course the foam collapses when you feed, but the Tunze produces foam more quickly after feeding than the Aqua C.
These comparisons are suspect. My Tunze is the lastest model availible and my Remora is old. They are on completely different systems: the Tunze a 10 gal with moderate fish load and the Aqua C on a 45 gal full reef with VERY heavy fish load. The Remora is helped by a BackPak on the same tank, both cups need to be emptied and cleaned daily. The Tunze sits IN the tank and therefore there are considerations if you have a hood. The Remora sits BEHIND the tank and therefore is better with some lighting fixtures.
hmmmm....is there anything I left out?
