Review: Worked great on my reef - My phosphates went through the roof and I lost a lot of my corals. Added this and it was easy to set up and started running gfo through it instead of a filter sock. Levels dropped within a week. Going to add another to run with carbon. Review: Good product - I bought this product, and the pump was very loud at first. I contacted customer service, and they sent me a new pump, which solved the problem. I’m also satisfied with the product—I’ve been using it for two weeks, and it hasn’t leaked even a single drop of water. ## Features - Up-flow filtration design helps maximize filter media performance—ideal for use with phosphate sponges, carbon, and resin-based media - Includes AQUATOP’s SWP-230 submersible pump with sediment discharge filter—supports clean, consistent flow during operation - Durable acrylic housing with recessed O-ring lid—designed for easy access and secure media changes without hassle - Comes complete with intake/output tubing, suction cups, and tank hook—versatile mounting for sump or hang-on installation - Includes tank hook and suction cups for flexible mounting—install the reactor securely inside a sump or hang it on the side of your aquarium ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00GYG54O6 | | ASIN | B00GYG54O6 | | Best Sellers Rank | #66,122 in Pet Supplies ( See Top 100 in Pet Supplies ) #322 in Aquarium Filters | | Brand Name | Aquatop | | Color | Multi | | Customer Reviews | 4.0 4.0 out of 5 stars (520) | | Date First Available | November 27, 2013 | | Flow Rate | 2 Gallons Per Minute | | Global Trade Identification Number | 00819603014037 | | Included Components | AQUATOP MR-20 Multimedia Reactor with Pump | | Is Discontinued By Manufacturer | No | | Item Dimensions L x W x H | 3.5"L x 2.5"W x 15"H | | Item Type Name | AQUATOP MR-20 Multimedia Reactor with Pump | | Item Weight | 4.54 g | | Item model number | MR-20 | | Manufacturer | Aquatop | | Manufacturer | Aquatop | | Manufacturer Part Number | 003567 | | Material Type | Resin | | Maximum Lifting Height | 15 Inches | | Model Number | MR-20 | | Power Source | Corded Electric | | Product Dimensions | 3.5 x 2.5 x 15 inches; 0.16 ounces | | Product Style | Multimedia Reactor with Pump | | Specific Uses For Product | aquarium pump | | UPC | 781163721697 819603014037 | | Unit Count | 1 Count | | Voltage | 110 Volts | ## Product Details - **Brand:** Aquatop - **Color:** Multi - **Item Weight:** 4.54 g - **Material:** Resin - **Maximum Flow Rate:** 2 Gallons Per Minute - **Maximum Lifting Height:** 15 Inches - **Power Source:** Corded Electric - **Product Dimensions:** 3.5"L x 2.5"W x 15"H - **Style:** Multimedia Reactor with Pump - **Voltage:** 110 Volts ## Images ![MR-20 Media Reactor – 95 GPH Up-Flow Filtration System – With Pump, Tubing & Mount – For Saltwater or Freshwater Aquariums – Sump or Hang-On Design - Image 1](https://m.media-amazon.com/images/I/71E1F5+gz7L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Could you put sand in this and use it as a fluidized bed filter?** A: I do. I put filter floss under the sponges to prevent sand from falling to the bottom. Used pool filtration sand and branched off from my primary pump with a valve to adjust water flow. I don't use the included pump but I don't see why you cant. Works great for me! **Q: Is the pump that it comes with a submersible or not** A: I'm confused how any pump that's not submerged would even work? That's kind of the point of the pump, to be submerged in water so that it pumps into the media... **Q: What are the exact internal diameter of the hoses?** A: From what I can measure, its 7/16 in. inner diameter and 1/2 in. outer diameter **Q: What size tubing I can use for the aquatop Mr 20 to replace the clear tubing that came with it with a black tube ?** A: 7/16 inch inner diameter, 1/2 inch outer diameter ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great on my reef *by B***S on May 29, 2025* My phosphates went through the roof and I lost a lot of my corals. Added this and it was easy to set up and started running gfo through it instead of a filter sock. Levels dropped within a week. Going to add another to run with carbon. ### ⭐⭐⭐⭐⭐ Good product *by M***T on April 4, 2026* I bought this product, and the pump was very loud at first. I contacted customer service, and they sent me a new pump, which solved the problem. I’m also satisfied with the product—I’ve been using it for two weeks, and it hasn’t leaked even a single drop of water. ### ⭐⭐⭐⭐ Very good for the price *by K***H on September 1, 2024* I have been using this as a gfo reactor for a while now and It does a good job. Only issue is the suction cups don't seem to wanna hold the hoses very well and they slip out from time to time and are more noticeable in the tank. Cleaning isn't hard but is still harder than I would like. The sponges get clogged up fairly easily and can cause performance issues if u don't stay on top of your maintenance. Over all I will buy another one for my other tank. The hang on option is good but it is better suited for a sump. ## Frequently Bought Together - Aquatop Media Reactor, 95 GPH – Up-Flow Filtration for Water Treatment – 10-75 Gal – Adjustable Water Pump Included – Reliable Filtration System - Kolar Labs GFO Bayoxide E33 Phosphate Remover – for Freshwater and Saltwater Aquariums, Reef Tanks, Promotes Coral Health (454g) - Marineland Black Diamond Premium Activated Carbon, Filter Media For Aquariums, 40 Ounces --- ## 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.gr/products/2956419-mr-20-media-reactor-95-gph-up-flow-filtration-system](https://www.desertcart.gr/products/2956419-mr-20-media-reactor-95-gph-up-flow-filtration-system) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-02*
