Review: Best protein skimmer on the market - I’ve had many protein skimmers over the years and this is by far the easiest to use. It’s very durable and does the job better than the others I’ve used. Perfect size for my 60 gallon sump and very quiet. I recommend for anyone looking for a skimmer that will get the job done. Review: Reef octopus skimmer - Love that it installed very easily. Functions as described. Makes millions of bubbles! Not 100 percent silent but not noticeable. Very well made. Worth the price because it’s definitely doing what it’s designed for. I have a lot of fish and feed a lot and this helps tremendously . ## Features - High Performance Venturi Air Injection System - Reef Octopus Aquatrance 2000s Skimmer Pump - Refined Hybrid (half cone) Skimmer Body - Solid Acrylic Construction - Quiet and Energy Efficient Operation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N45H3YO | | Best Sellers Rank | #116,576 in Pet Supplies ( See Top 100 in Pet Supplies ) #1,643 in Filters (Pet Supplies) | | Brand | REEF | | Brand Name | REEF | | Customer Reviews | 4.4 out of 5 stars 66 Reviews | | Item Form | Liquid | | Item Type Name | Pet Supplies | | Item Weight | 2.27 kg | | Liquid Volume | 150 Gallons | | Manufacturer | Reef Octopus | | Manufacturer Part Number | CLSC-150INT | | Model Number | CLSC-150INT | | Net Quantity | 1.00 Count | | Pet Type | Fish | | Target Species | Fish | | UPC | 735343871986 793842666809 695029125188 950291202877 782195450005 | | Unit Count | 1.00 Count | | country-of-origin | China | ## Product Details - **Brand:** REEF - **Liquid Volume:** 150 Gallons - **Item Weight:** 5 Pounds - **Item Form:** Liquid - **Manufacturer:** Reef Octopus ## Images ![Octopus Classic 150INT in-Sump Protein Skimmer - Image 1](https://m.media-amazon.com/images/I/51z887fRTPS.jpg) ![Octopus Classic 150INT in-Sump Protein Skimmer - Image 2](https://m.media-amazon.com/images/I/61qQZfOyn3L.jpg) ![Octopus Classic 150INT in-Sump Protein Skimmer - Image 3](https://m.media-amazon.com/images/I/41HArWFEiUL.jpg) ![Octopus Classic 150INT in-Sump Protein Skimmer - Image 4](https://m.media-amazon.com/images/I/61MlmxONfaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best protein skimmer on the market *by P***K on 6 December 2025* I’ve had many protein skimmers over the years and this is by far the easiest to use. It’s very durable and does the job better than the others I’ve used. Perfect size for my 60 gallon sump and very quiet. I recommend for anyone looking for a skimmer that will get the job done. ### ⭐⭐⭐⭐⭐ Reef octopus skimmer *by S***N on 7 October 2024* Love that it installed very easily. Functions as described. Makes millions of bubbles! Not 100 percent silent but not noticeable. Very well made. Worth the price because it’s definitely doing what it’s designed for. I have a lot of fish and feed a lot and this helps tremendously . ### ⭐⭐⭐⭐⭐ Great skimmer, excellent peformance once broken in. *by A***N on 2 August 2018* Great skimmer! Took a little time to break in. I read that you can put the emptying tube into a container and just remove from tank rather then overflow. After a few days of overflow from skimmer to the socks I decided to try it. I emptied about a gallon in a few hours and then the skimmer was basically broken in. Another week to really dial it in. I have been leaving it rather wet in order to keep the main body clean. I just clean the collection cup every few days and it is way easier to do preventative maintenance like that then remove the whole skimmer once a month or several months even. The collection ranges from dark green/yellow to nearly black and smells awful when emptying however no bad smells in my office near display tank. Free Tip: use a zip strip with some foam filter floss on the output and you can get this skimmer to almost silent and no bubbles in return to sump. ## Frequently Bought Together - Reef Octopus Classic 150INT Protein Skimmer - CaribSea Arag-Alive 20 lb Fiji Pink Sand --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/77368628-octopus-classic-150int-in-sump-protein-skimmer](https://www.desertcart.pt/products/77368628-octopus-classic-150int-in-sump-protein-skimmer) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-02*
