Excellent quality and design for the price. By Tony on 2/1/12Tony would recommend this product to a friendI bought this unit to replace a Precision Marine unit that I sold. The construction is "as good" if not better than the PM I had. This unit has some very good logic and design functions: The CO2 diffuser is very intuitive and should be standard for all Ca reactors. I also like the CO2 recirculation setup to be more efficient. The miscellaneous chamber is also nice for adding other substrate to the effluent heading back to the tank. Originally, I was going to use Phosban, but was hesitant because of the possible PH reaction, so I'm using ZEOmag as a sequestering agent to avoid Calcium precipitation...and my invitro testing show that it definitely helps.
Wow By Alex on 7/6/11Alex would recommend this product to a friendIn a word “Wow”, if you’re in need of a calcium and alkalinity solution and/or you’re on shoe-string budget then this is the reactor for you!!! I’m extremely impressed on how well-built this thing is!!! It’s comparable to more expensive units I have on my 200gal tank, the extra chamber is awesome and has many uses, and the co2 diffuser was and is a smart addition… I’m using 5-parts Elos Ca-Pur to 1-part ZeoMag in the main chamber and additional Ca-Pur in chamber 2 to keep my PH high… Overall great unit and I and do recommend it to anyone!!

Great Reactor By Phillip on 4/22/11Phillip would recommend this product to a friendThis thing is a beast, if you need a calcium and alkalinity solution and you are on a budged you need to get this reactor, it works great even comparable to more expensive models and other brands, the extra chamber is awesome and has many uses, ad the co2 difuser is a smart addition too. Overall great unit
looks complex but isn't By Mason on 11/12/10Mason would recommend this product to a friendthis reactor doesn't have the homemade or cheap feel other reactors in this price range have. The effluent also has a higher PH than my old coralife reactor. I'd buy it again.

Can it runs outside of the sump? If it can, do I need to purchase another water pump for that purpose?
Bulk Reef Supply Hey Even,
It certainly can. That is how they are almost always used actually. You wouldn't have to purchase a separate pump because you are putting it outside of the sump, but you do need to get a feed pump either way. The pump that is on the reactor itself doesn't actually feed water into the reactor, it just recirculates (and mixes in the co2, etc).
You would want some sort of small pump to slowly push water into the reactor. The most popular pump for this application is the aqua-lifter pump. It is a great option if your only needing to pump a few feet to the reactor.
Stable parameters are the key to a successful reefscape. Calcium, being utilized by a myriad of oceanic life forms including corals and crustaceans, is amongst the most important of these parameters. As the fifth most abundant ion found in natural saltwater, it is absolutely critical that Calcium is kept at a constant. One of the greatest pieces of equipment aquarists has at their disposal to maintain this parameter is the Calcium Reactor. By dissolving Aragonite-based mediums down to their basic elements, Calcium Reactors allow for a continuous influx of calcium into the system.
Vertex RX-Series Calcium Reactors now bring this potent tool home to you with all the features and qualities you need at values you can easily afford.
Efficient and Easy to Use
Designed for maximum capability, Vertex RX-Series Calcium Reactors feature an advanced recirculating chamber design, allowing for extremely proficient use of media and CO2.
A large bubble counter makes for easy visibility and effortless adjustments. Fine tuning of flow/effluent is also straight-forward with the high quality Vertex Needle Valve included with each reactor.
Vertex RX-Series Calcium Reactors utilize the exclusive Gas Stable Use (GSU) concept to aggressively dissolve CO2, recycle unused CO2, and extract only reduced CO2 effluent. As a result, Vertex RX-Series Calcium Reactors are more efficient than other available designs.
Vertex™ RX-Series Calcium Reactors are made to last; being assembled with only high-grade cast acrylic and heavy-duty PVC parts. All Vertex products are rigorously tested for safety, efficiency and reliability.
