Coral Vue Technology AC20284 Octopus Needle Wheel Skimmer for Aquarium Filter, 4-Inch, 100-Gallon

Very good

Excellent skimmer

Es un Skimmer totalmente funcional

Small profile, which is good because I have an undersized sump. Easy to assemble in less than ten minutes. Works well right out of the box. I had no break in period. This replaces the same model I purchased five years ago. That's about standard for any skimmer I've used.

I had originally purchased a coralife super skimmer as a HOB skimmer because it also functioned as an in sump skimmer had I ever decided to make the switch. About two months after purchasing the coralife super skimmer I went and added a sump to my system. The Coralife super skimmer worked ok as a HOB skimmer but terrible as an in sump skimmer. It was never consistent, constantly overflowed, and never produced a skim. I honestly don't know how I went 6 months with this skimmer not working and my corals still thriving. Now to the Reef Octopus skimmer which I just purchased. Works great. First thing I noticed was a much better construction than my previous coralife skimmer. The skimmer cup is friction fit into the protein skimmer on the reef octopus which is very desirable as it was never easy to screw the skimmer cup back onto the coralife super skimmer. The airline hose is much thicker, and the air silencer is clear with much larger holes than the coralife skimmer. This is extremely important because my coralife super skimmer would clog in two days tops because of salt creep, and any fluctuation in the air intake on a skimmer will cause it to overflow. I've had my reef octopus running for two week and have had no salt creep issues or calcium buildup in the air intake line. Actual performance: Took me about a week to really get the reef octopus broken in and tuned to work optimally with my system. Now that it I have fine tuned it I am getting an thick skim and am seeing all of the junk that is being removed from my tank. Finally a skimmer on my system that works as it is suppose to.

Muy buen espumador y muy practico para limpiar

I put this on a 40b display + 20g sump system. It replaced an SCA301 skimmer. Out of the box: dead silent. Huge amount of foam and microbubbles. No gunk getting skimmed out, just a ton of foam. Then I left it alone and went on vacation for a week and a half. Now: Not super silent, but still very quiet. The cup is full of very dark skimmate. Being able to detach the cup easily means it's very simple to clean. The SCA skimmer is in storage and I still need to clean it but the difference in performance is extremely impressive.
