AQUATOP MR-30 Media Reactor – 152 GPH Up-Flow Filtration System – with Pump, Tubing & Mount – for Saltwater or Freshwater Aquariums – Sump or Hang-On Setup

Everything works perfect. Easy to put together got the reactor running in probably 10 minutes. The only thing I don't like is that the unit is to big, other then that thumbs up. Fyi I looked at some of the reviews about the pump problem and I don't think that's the case. Attached is a video showing how is working perfectly, the GFO needs to tumble gently you don't need an earthquake inside the reactor. So far everything working good 👍 I recommend the unit.

Works really well however here I am 1 year later and one of the screws is rusted and I now have contamination in my tank that has cause all my soft coral to close, my Montiporia to bleach and some of my shrimp to die….

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.

The reactor comes with everything you need including all hoses and mounting components for wither free standing or hanging on the tank itself. I read the reviews prior to buying and many said the pump was too small. It is rated at 152 GPH. It is advertised as being able to accommodate up to a 200 gallon tank. The actual flow through the reactor was pretty slow and was not doing a good job passing the water through my carbon that I put in the reactor.. After additional research, I found that most experts recommend turning over your tank volume at least 4 time per hour. For my 125 I needed a pump that had at least a 500 GPH flow rate. I purchased a new pump with a flow rate of 580 GPH and hooked it up to the reactor hose. Now I am getting great flow through the reactor and it is doing a much better job. The new pump was only $18 which I bought here on Amazon. I hope this helps anyone looking to buy this reactor. The price was great but the pump is definitely undersized for a larger tank.

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.

The pump that was included lasted only for FIVE (5) MINUTES! Now I'm stuck looking for another pump. Another reviewer said that the pump wasn't strong enough. Now I don't know what to buy. Meanwhile....the reactor is set up and ready to go.....but I can't use it. I would also like enough tubing to have the reactor under the tank, rather than behind. It is heavy when it is full and I don't know if I want all that weight on the back of my glass aquarium. Not only that, but there is barely enough clearance to put it on the back of the tank and it scraped the wall! Now I have to add "touch up paint" to my To Do list. Along with having to purchase another pump! (And, they don't give you enough tubing if you want to put the thing under the tank). I'll update this review if I ever manage to get this thing working...... Right now I am extremely unhappy that I spent all of this money and I can't use the thing.

Weak pump. Besides that it a good product so far. Been in use for a week now, with a larger pump.

Ihear people raging the little pump they they give with this reactor ,well there dead wrong it's plenty strong enough to push water up and back through the media. Im Using it for a calcium reactor and what your not I hear people raging the little pump they give with this reactor ,well there dead wrong it plenty strong enough to punch water up and back through the mefia what ever your using. I. Using it for a calcium reactor and what your not understanding is a slow flow filters better than a fast one , that a scientific fact . this reactor keeps my reef up to 425 ppm on calcium with no problem.
