Bought this 7 months ago and hooked it to my sump with a float and it has not missed a beat. It keeps my water level where it is supposed to be with 0 TDS water. Also installed a "T" fitting to allow me to fill bottles for my nano tanks at work. This RO unit is definitely worth the money.

I did a bit of research (forums, youtube, etc...) on what to look for in a RO/DI system and made a list of component and manufacturers. As I've stayed really pretty loyal to BRS I was happy to see they had a system. I was even happier when I read the reviews. I was EVEN happier when I got it and set it up in a matter of minutes. Just let it run off for a while and everything read great! Maybe wish I went with a 150GPD, but only because I'm impatiently setting up a 180g! Ha!

Very happy with this system, comes with everything needed for just about any application. The float switch will be great when I add a poly storage tank, glad to see that was included. I've only had the unit a few months, but has worked flawlessly. Other than the filter monitor Velcro falling off (which i knew it would from others reviews and it did the first or second day) I don't think I could have bought a nicer system for twice the money. Super happy, thanks BRS

New to saltwater my LFS recommended BRS. The BRS 6 stage unit as provided all the 0 TDS water needed to start and maintain my tank. Mounted, plumbed and created water within 60 minutes of arrival. The non-leaking quick connects, easy change filters make this system a winner.

I'm writing this review because I was a big skeptic and felt this was just cheap, cheap rodi for reefers on a budget. Well my high end over priced rodi needed complete filter replacing but lucky a close friend was breaking his tank down and offered me this 6 stage. I was a little skeptic but more of a critic....well I did the research and i did the test against 3 other units.

The first sediment is a purtex 5 micron? What! I was accustomed to .5 micron but soon learned the purtex will filter up to .6 which means it will clog later and the longevity is higher. The larger particles get filtered earlier and in the end the water has to pass through .6 micron so that's a win and its a lot cheaper. Then the carbon which is 2 and 3 chamber and of course it's laid out just as good if not better than others. The Dual Di is just that DI so no need to add to that but the membrane is filmtec and has a 99%@ 65psi rejection rate....what! I was hoping for a little better than 96% but this is a big plus. The other company charges more for membranes for so called test but we know 75gph membranes are known for its ejection rates. As a matter of fact they removed their 75gph membrane and listed it sold out for years since I checked. All they are doing is selling them as 90gpd and charging 10% more for tested...chances are if u buy a 75gpd membrane it will have a high rejection rate, it's cheaper on here btw. Everything on this unit is top notch, yeah we all heard it before but this is the real deal.

I don't know how I feel about the filter monitor and isn't user friendly. To reset the unit is easy but I guess that's all it really does do? It's like a timer and reads the amount of water that passes and after a certain gph it will tell u to replace which filter. Time will tell but I'm accustomed to the age old gauge but this has both and a high end oil filled gauge. The in line tds with self shut off is pretty sweet, I have used the older models and this new one is just as good but more visually pleasing to the eye with lager display. I'm very happy with this unit and would of saved a ton have I read more detailed reviews on specs so the reason for this. All in all this is the most affordable rodi with highest value on the market. Yes, I checked everyone but given their reputation and value no way I would even consider a diff brand. They don't try to rip and make a reasonable profit. I have no problems with to continually support a company as such.

*********Fyi when originally getting this unit I was ready to write a negative review but after personal use and comparing with two other brands. Brs, why did I doubt you.

Dual DI is the way to go. I have an extra resin container and keep it ready to go. When the TDS climbs from zero, you remove the inlet side DI, swap the outlet Side DI to the inlet side, and replace th outlet side with the fresh one. This rotation works very well.

I've had my unit for a year now and have had zero issues. My filters lasted just over a year or ~3500 gallons. This system fills up a 5 gallon bucket in about 2 hours. I've been very happy, 0 tds every time. When I called buck reef supply for replacement filters they were very helpful. I'm a very happy customer.

Never had a problem with BRS products. This RO/DI system does it all. It comes ready to go plug and play. Filters last a long time.

I have been running this 6 stage unit for 60 days now and I can't say enough good things about it. As with everything I buy from BRS it seems to be a top quality product. But more importantly, BRS stands behind all that I buy and are wonderful to deal with.

If you have the money to get this setup, do it. For the amount of money you have invested (or about to invest) in your tank, start with the best water you can get. I am getting 0 TDS out of the DI canisters.

Install time took just minutes. All of the connections are extremely high quality and well worth the money you spend on the setup. The drain saddle clamp is awesome, I have my setup next to my water heater and well pressure tank, with the drain hooked up to one of my bathroom drain standpipes. The only concern I have is with backflow of the drain water into the waste line - I'll be ordering a check valve from BRS to alleviate that concern!

The connections provided with the kits are perfect, any situation you can think of for hooking up is provided for. No hunting down parts at the local hardware store!

The filter minder and upgraded TDS meter, as well as the flush kit and oil filled gauge- all top notch. Let's face it, as reefers we tend to upgrade things all the time and regret buying the lower end products (I for one have a box of things I've upgraded). Just go for the deluxe setup and go for all the high end stuff now!

what I like about this filter is that it is ready to go out of the box with all the connections already made, perfect water quality. zero TDS coming out everytime. well made filter with quality filters.

Have had this system going now for about 5 months and I am very pleased with the value and performance this has given so far. Hassle free installation took less than an hour. I do reccomend the 150 GPD upgrade for those with larger tanks who will be changing a larger water volume on a regular basis. The built in TDS meter is very useful in knowing exactly when you should change the resin out. I highly reccomend this RODI unit to any serious marine aquarium hobbyist.

I have used a 5 stage system before and thought it was a great system, then I found the BRS 6 stage deluxe system. This thing is great, absolutely zero TDS coming out. On my old system the TDS started creeping up after a few months of use. I am on well water so the water pressure is a bit of a problem but it still will fill up a 5 gal. Bucket in about an hour on a good day, a little longer when the pressure is down. I also got the add on drinking water system which the wife loves ( we all know how important it is to keep the wife happy) Filtered drinking water on demand is awesome...now all I need is a booster pump to reach the full potential of this filter.

I love the quality of water, but one of the features I don't really use. Instead of the filter monitor, I'd prefer another dual TDS on the RO unit since that helps me know when it's time to change the media better than the volume of water produced. I love 0 TDS water and my tank has never looked better. Great product :)

I bought a RO/DI unit from a lfs, but returned it because it cost more and had less features. The float valve is great, I don't have worry about water overflowing. This system comes with everything you need. This is a high quality unit and a great value.

Excellent quality system and easy to install. Occasionally I test the water and it comes up with no nitrates every time. It is so much easier do to my water changes now.

I bought this system because I knew that I would need to have a nice reservoir of fresh RO/DI water ready for my marine tank and driving back and forth from the LFS for water just didn't seem like a good idea.

I got the unit in a nicely packaged box from BRS and I could tell right away that it was a quality product. The materials used to make this system are top notch and it was incredibly easy to setup. I followed the instructions and was creating RO/DI water in no time. I wanted a more “automated” solution, so I decided to make a direct and permanent connection to my house’s water supply. BRS also has videos available to show you how to do that and it was pretty easy to do.

I now have a self-filling (with float valve) RO/DI system that I am very pleased with and makes the tasks of topping off my tank or mixing salt water a breeze.

The attention to detail with this RO/DI system is outstanding. BRS uses high quality parts to build these systems. Everything is put together for you. Only thing you have to do is unpackage it, and install the source, drain and product water lines. EASY!

This is an excellent system that includes a lot of the small parts and pieces that you don't think of ahead of time, but end up running to Home Depot to buy last minute. This system illustrates how much forethought and purpose-specific insight goes into BRS' products: they truly tailor their products to the conscientious reefer.

While the 5 stage might be a better price, this system includes things that you'll probably end up purchasing for the 5 stage system anyways, and because of that, it's probably worth it to purchase this unit instead and have all the things you need from the get-go. Definitely recommended.

This is the system that I have. The velcro really does fall off, but itsokay just get some different type of velcro. The TDS meter is secured in a bracket and it is pretty nice. Mine however does not work anymore, I just purchased the RO/DI system a few months ago. I have emailed BRS, no answer? Maybe I need to email again? Other than that nice product. Very easy to set up.

I was able to install this in less than an hour including mounting some plywood to the wall and installing a Y connector on my washing machine cold water faucet. Once installed I had water coming out in about 5 minutes.

Very nice RO/DI filter. BRS again sets the standard. Very well made filter.

This is a great system with all the bells and whistles you'll need to get up and running quickly, plus you get perfect water with zero TDS. For years my FW planted tank was problematic while other tanks looked so nice but after my first 40% water change the water was crystal clear and my sediment problems gone, don't wait because you do need one dispite what others might tell you.

I looked everywhere else and this system is the best value for the money. Everything needed for the install was included in the kit. The filter replacements are the best and can be found everywhere, but again Bulk Reef Supply has the best pricing on them too. My results were 3 gallons waste water for every gallon RO/DI produced at 70psi and 75 deg. Easy install, lots of extras with this package. Thanks
