## Overview

The AQUATOP MR-30 Media Reactor is a 152 GPH up-flow filtration system designed for both saltwater and freshwater aquariums up to 200 gallons. Featuring a reverse water flow to maximize media efficiency, it includes a reliable submersible pump, durable acrylic chamber with easy-access lid, and all necessary tubing and mounting hardware for flexible sump or hang-on installation.

## Description

This powerful reactor uses a reverse water flow design that prevents water from channeling through the filter media, thus maximizing the efficiency of filter media. Constructed of high quality acrylic with an easy to remove lid, the MR Series can be installed either in-sump or hang on the tank and comes complete with all plumbing parts.

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: Nice reactor, small enough for chamber on BioCube 29. - Was looking for a reactor that would fit in the back chamber of my BioCube 29 and this fit the bill. Pump has fairly low output as many reviewers have stated but it works for me so far with PhosGuard. A larger replacement pump is so cheap that I'm not concerned about the output. I'd buy it again.

## Features

- Up-flow filtration system helps maximize the efficiency of filter media—compatible with carbon, phosphate sponges, and resin-based media
- Includes AQUATOP’s SWP-360 submersible pump with sediment discharge filter—provides stable water movement during operation
- Sturdy acrylic chamber with recessed O-ring lid allows for quick, secure access to internal media for simple replacement or cleaning
- Complete with intake and output tubing—easy to connect and position within your aquarium’s filtration setup
- Includes tank hook and suction cups for flexible installation—mounts securely in sumps or hangs on the side of aquarium tanks

## 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

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Nice reactor, small enough for chamber on BioCube 29.
*by M***X on August 29, 2023*

Was looking for a reactor that would fit in the back chamber of my BioCube 29 and this fit the bill. Pump has fairly low output as many reviewers have stated but it works for me so far with PhosGuard. A larger replacement pump is so cheap that I'm not concerned about the output. I'd buy it again.

### ⭐⭐⭐⭐ 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.
