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!
