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.
Nice quality, one serious flaw By networkcrasher on 11/8/2018networkcrasher wouldn't recommend this product to a friendThe design of this reactor is such that the pump connection between the main reactor body and the CO2 input and recirc loop has to be connected very precisely. There is little to no room for error due to the hard connections between the pump. If Vertex assembled your unit properly, it'll likely work right. If they are off by as little as a few mm, the unit will either leak, or the pump will be pretty noisy as the impeller is stuck at a bit of an angle and rattles. It's hard to describe until you see it in person.
The serious flaw of this thing is the union is glued into the pump, so if you ever have a failed pump, good luck getting it replaced. Vertex support may, or may not, answer your emails, and even then, you have to convince them to send you a pump. The union they use doesn't seem to be one widely available on the market, so you can't just make up the connection yourself. I suppose you might be able to destroy the old pump in an effort to get out the union connection, but good luck with that!
The bubble counter is pretty useless unless you're running a ridiculously high flow rate through it. Although, I'm pretty sure you have to run a high flow rate through it in order to keep the noise of the pump chopping up CO2 bubbles, which I sort of think is unavoidable if you set it up as designed. The recirc loop sort of forces the gas back through the pump, so unless you have more flow going in to allow for more CO2 dissolving, I imagine yours will chop bubbles too.
Other than the serious pump flaw, the quality is typical Vertex. It's quite nice. Good news is if it fails, you can still use the secondary reactor on any other CaRx you buy!
Good. Solid construction. By Robert on 9/24/2018Robert would recommend this product to a friendWorking very well. Definitely follow instructions and apply silicone to recommended connections. No problems with leaks.
Works Great! By George Jansen on 8/30/2018George Jansen would recommend this product to a friend120 SPS tank... was spending so much money on 2 part - this saved the day. It is an investment to get started, but keeping alk and Ca constant has been awesome. I should've gotten one a long time ago. The build quality is awesome, sounds like a few people had leaks.. I had that too then was instructed to reassemble the unit. that worked! must have assembled it wrong the first time
Solid build By Jack L on 5/17/2018Jack L would recommend this product to a friendGreat product, keep my ALK at 9 on a moderate 250G Mixed reef with no issue.
everything worked great, great packaging, first class! i was on the fence reading the reviews but now after 5 weeks extremely happy with the purchase. no leaks no issues Adam at Vertex walked me through the set up as well since i was too lazy to read the manual :)
Nice and functional By Vladimir on 11/7/2017Vladimir would recommend this product to a friendWork for me, no leaks, good quality similar to omega skimmer.
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!
