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.

With a reputation like Reef Octopus skimmers have, my review really doesn't matter much. Using in a Eshopps sump and cannot ask for better results. Expect a break in period of 1-2 weeks before you get any real results of skimmate, so don't get discouraged wait for the setup to work. You will also need to find the perfect balance for your sump setup and air vs. flow mixture using the flow valve, which changed once it "broke in". When it did, it produces! My 90 gallon reef tank creates enough where I have to empty it about every 3-4 days+ and it is nasty green/brown stinky skimmate... better out than in right? if you are going on a vacation... it does have a drain plug on the collection cup to setup if desired.Otherwise you get get a much better sump skimmer for the value and price than a Reef Octopus.To compare... I also own a Aqua-C Remora (another great skimmer) from another tank (hang on tank model) and the reef octopus produces wet skimmate more than the drier skimmate that the Aqua-C makes (totally different skim methods though. I would have used it but the rating is for 75 gallons or less.Add a comment before you say not helpful I will try to reply. Thanks.

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.
