Great design ( other then pump) poor service vertex By David on 12/23/2019David wouldn't recommend this product to a friendThis is a review from someone using this for over a year. great calcium reactor when you first get it. Problem comes when you need replacement parts. Specially the only part that will probably go bad which is the pump. Nobody sell them you have to contact Vertex which can be nightmare.( also heard there going to stop selling in the USA ). Bought this because of all the BRS videos raving how good it is. But one point they didn't make was when looking for calcium reactor is pump design companies that use normal of the self pumps are way better in design usually that the only part you would have to replace. So if your in a pinch and pump goes out you can easily find a replacement.
Terrible After sales service By Hans on 11/22/2019Hans wouldn't recommend this product to a friendBAD SALES SERVICE WHEN SOMETHING IS WRONG. Although a great product that works well the real danger is when there is a problem. Out the box I had an issue with the pump, once of the rubber grommets on the impellor shaft was missing. I got hold of Bulk Reef WHO in turn handed me over to Vertex. THIS IS WHERE THE PROBLEM STARTED. Bulk Reef should take responsibility for the products they sell and should be my only point of contact, they after all have the sales agreement with Vertex and the leverage. It has been two weeks of waiting with no solution from Vertex. They seem to only answer emails and respond once a week. Still waiting for my last email to be responded too. Out of frustration I have bough another pump in order to get the missing part and finally have my reactor working. NOT THE WAY I EXPECTED THE PROCESS TO GO AND AN ADDITIONAL $60 OUT OF POCKET- BULK REEF PLEASE BE OUR SUPPORTER RHATHER THAN HANDING US OVER TO A NON CARING VENDOR. DONT LET US STRUGGLE WITH THE VENDOR, WE HAVE NO LEVERAGE - YOU DO!
Easy setup but noisy By Ken on 11/12/2019Ken would recommend this product to a friendI just received my Calcium Reactor. It was easy to assemble and set up. However it is noisy. I saw someone that switched the hoses connecting the auxilary canister with the CO2 recirculation line. That quieted it down. However the pump still rattles just enough to be heard over my very silent set up.
One thing that I think could be improved is the screw top canisters. Other reactors use a flange with holes and thumbscrews to hold the top down. This allows you to remove the top without requiring the hoses to be disconnected. With this reactor, you have to disconnect hoses in order to remove the top when you refill. Its not that we have to do it all the time, but it would be a nice improvement.
So far (2 days), this has been a good set up. No leaks, and easy setup. Albeit, a little loud.
Great design, material/build quality issues By Chuck on 10/20/2019Chuck would recommend this product to a friendSo I’ve owned one of these for a little while now and can say that it is a pretty decent calcium reactor. However, I have a few issues with some of their materials and/or build quality. Out of the box everything worked great. But, on my third, fifth, and sixth time taking it apart to clean and change the media, it broke. The red pipe connecting the pump to the main reactor chamber broke off. I wasn’t even forcing it off or anything. The unit came apart at the seems. On the fifth time, the red tube broke. The company was worthless in their support for the issue and only offered to sell me a new main chamber (for close to the same price as a new unit). Luckily I have had experience with (and had the glue) acrylic gluing. I was able to glue the unit back together. It “seems” to work and doesn’t leak, but their product is made from an acrylic that doesn’t take well to the acrylic glue very well. It may just be my experience, but I would advise picking up some acrylic glue and a needle applicator when you buy the unit.
Started great, support awful By Will on 9/22/2019Will wouldn't recommend this product to a friendI purchased this unit a couple years ago. A few weeks ago the pump died. I tried contacting vertex to find out what parts I need. Receiving responses from them was like pulling teeth. If I wanted to call their support number they don’t pick up their phone and then voicemail is full. I tried to get bulkreef supply to help me with them and they passed me off as it’s out of warranty and they stopped responding to me as well. My tank is suffering and corals are dying due to not being able to get the support I need. Do yourself a favor and stay away from vertex and brs if you value any kind of after purchase support. I say this after being a customer of both for many many years.
Great Calcium Reactor By Marco on 6/10/2019Marco would recommend this product to a friendHad a little leak at first but was my fault i didn’t tighten it all the way
After that no issues. The only thing that keep me from giving it 5 stars is that if air gets in the pump it is really loud for a few days till the air gets out, then pretty silent with no issues.
LOUD but decent unit By Derrick on 5/30/2019Derrick would recommend this product to a friendSo I have had this running for about 3 months. I can tell you mine did not leak. I made sure everything was nice and tight. I am using the Kamour duty pump and what a breeze it is with this thing. It works very well as a CaRx. The reason for my 3 stars is the following.
- If you move this thing the pump surges nonstop and this is the loudest thing I own on my tank. It takes easily a day or two for it subside.
- Replacing media is very difficult. First taking off the cap is quite difficult. Once you turn everything off and remove the cover water goes everywhere. There should be a way to remove some of the water for cleaning and media replacement.
- If the pump gets a tiny bit of air in it game over. SO LOUD.
Leaks, disposable By Ari on 5/6/2019Ari wouldn't recommend this product to a friendYou would want to buy this because it’s rated highly by BRS and why would you? You should base it on the reviews about this product. Honestly, it’s very easy to setup but it will leak... if not right away, soon. It will leak on the pump attachment, it will leak on the cover, or any screw in type caps. Vertex uses push connect fitting which is really such a breeze to install tubes. But the attachment of the push connect are not reliable. Good luck fixing it with weldon or silicone once it leaks as vertex don’t have any accessories of sort for their product. BRS can help you but once it gets wet even a sprinkle they’ll not accept returns. In the end, after a year of use, when all warranty expires, and when it’s time to maintain and replace the media,( believe me, it’s the most complicated and not very easy thing to do)- pray that it doesn’t leak. Well, at least you are left with indestructible plastic and maybe, you can sell those titanium screws they added! Such a joke!
Great Reactor with some drawbacks. By Walnutclown on 3/15/2019Walnutclown would recommend this product to a friendThis is a great reactor. Solid build which is expected by Vertex. Let me explain the few things I don't like.
1) Like many vertex items, the custom pump connection is annoying. If it breaks it is a pain to get a new one. Mine broke, because of my mistake, and the replacement part took weeks to get from Vertex USA.
2) The base everything sits on is silly. It should have been a solid piece all glued together. It's not a big issue, but part of the reason I broke the pump.
3) The threaded parts seal very well, but like Vertex skimmers, they are annoying to open and close.
Other then that, these reactors operate flawlessly. My issues aren't a deal breaker for me and I'd buy another one for my new tank.
Outstanding Build Quality By Eric on 2/25/2019Eric would recommend this product to a friendI get where people are coming from, I can see how this could leak if not setup correctly, but I haven't had that problem. I had read the reviews and was very conscious of this when I put it together. Outside of the leaking issue (which seems to be related to connecting the pump to the body), I can't find any issue with this reactor. High capacity, flexible footprint, very quiet, pleased with my purchase.
Leaks By Jose on 2/3/2019Jose wouldn't recommend this product to a friendIt is very hard to maintain and it leaks every where, I've had it for a year in a half and it's always caused me problems.
Cheaply Built By Jason on 12/24/2018Jason wouldn't recommend this product to a friendHad this reactor for about 7 months and it broke 3 times. The pump leaked twice and had to be sent off. Then I grab the reactor to fill it back up with new media and the plastic weld on the bottom pump joint broke off. Was told by vertex sorry no fix this time. 500 dollars worth of junk.
Ended up going with a skimz and it is a way nicer unit. Do yourself a favor and don’t buy this reactor.
How do I find a replacement for the re-circulating pump. It looks like it is just a Sicce 1.5 or 1.0 but it has attachments which are specific for the reactor.
How many pounds of media can this reactor hold?
This answer will unfortunately vary depending on the type of media used. With calcium reacotrs you will simply fill up the reactor fully and the amount of media will not impact, just how often the media will need to be replaced.
Has the leak issue mentioned by so many been addressed? What are your thoughts about this issue? Thanks
Hope this helps!
Does this reactor have to be put in the water or can it run outside of the sump and be fed a line from the the tank. Not a lot of room in the sump.
This can be plumbed either internally or externally no problem! Feel free to let us know if you have any further questions!
I am having troubles finding quality reactor with small foot print. Can this reactor be used with-out the base which would allow for a different configuration
This reactor can be used without the base to set up in a different configuration. Feel free to let us know if you have any further questions!
Does this calcium reactor come with one or more places to install a pH probe?
This will comes with one probe port. Feel free to let us know if you have any further questions!
What is the top chamber for above the secondary chamber.What ph,bubble count and flow rate to start with as a baseline
the secondary chamber is a second compartment to fill with media to catch any remaining lower pH water from entering the aquarium. The pH should be between 6.5 to 6.7 for a proper melting point and often 10 bubble per minute on average. Feel free to let us know if you have any further questions!
What is the absolute smallest footprint for this reactor, I am limited in my sump, and only have a 10 inch gap where I could fit this reactor. Would this work?
Unfortunately the smallest foot print for the reactor is 10.5 x 12.25 Feel free to let us know if you have any further questions!
