Hi, does anybody know where I can buy DOW FILMTEC TW30-3012-500 in Europe? Kind regards

Brand new in original packaging, BRS Six Stage RODI System. Included is a lightly used 8800 Booster pump but no power supply. I had a power supply go out on another RODI and stole it for that. They are easily sourced via BRS and other places. $300 for all + shipping.

Hello friends, Im planning to build a RO system with two 500 GPD membranes in parallel use (not in series) in order to get 1000 GPD at the end. The setup is roughly as follows: Sediment Filter -> Carbon filter -> Booster Pump -> Y connector which separates into two tubes -> two 500 GPD...

I have a barely used puratek rodi system with pressure pump and auto flushing membrane. Used as a backup to my 200gpd system. Here is a reference link, https://premiumaquatics.com/products/puratek-deluxe-100-gpd-rodi-filter-system-aquamaxx.html I will include new sediment, carbon block and a...

Hi guys, I have an small 30g tank which will need ~5g fortnightly changes Can't do much drilling in pipes and walls/kitchen as I'm renting the apartment Was looking for options on portable RODI systems that I can plug into the bathroom tap faucet directly, leave running for a few hours...

I see a lot of materials about protecting ro membranes from free chlorine and chloramines. However in my area the water is treated with chlorine dioxide instead, which results in the water containing chlorites and chlorates as opposed to the usual products. I don't have enough knowledge in the...

Hi all, so I was in the saltwater tank hobby for about 3 years and have been out of it for about 2 now with no tank. I recently found my old 13.5 gallon fluval EVO tank and want to set it back up. I’m looking to purchase a new submersible pump for it as that’s the only thing I believe needs...

So I have this issue where with both of my faucets I’m not sure they even have a thread I’m capable of accessing? I live in an apartment with a sink bathroom faucet and a kitchen faucet neither which seem like something I’m able to screw into? How would I even go about setting up a reverse...

Hello All, I have just acquired a new R.O. system and the water pressure is not enough to go thru it. Here in Brazil the proper R.O. pumps are very expensive, I was wonder if could use those motorhome ones, as long as they deliver the same or even higher pressures, the price difference is huge...

Will it be safe to use waste water from rodi to my freshwater tank?

Has anyone bought the water saver from brs? Any problems with it? I plan on getting one for my current system I have a 100gpd on 1:1.2 ratio and plan on getting the 200 gpd water saver upgrade kit.

Hello, who sell reverse osmosis of aquatic life, 100 gpd?

Its our Barrel Buddie!!! Smart Fill Controller uses an upper and lower sensor to detect the water level in a barrel or container. When water falls below the level you set, the controller will open the solenoid, so water fills your container. The solenoid will close when the water level...

After watching this video I have some questions. He mentions there are two ways to run dual membranes- in parallel or in series, however the "series" he describes is not actually in series- it is the "wastewater staging" setup designed to take the wastewater from one membrane and filter that...

This RO system is driving me crazy. I just replaced the membrane, carbon filter, and added a booster pump. It is still only putting out 10 tds even with the pressure increase and new membrane. With the old membrane & without the pump, it was putting around 14. Changing the membrane did not seem...

Hi Reef2Reef. Have a quick question about acceptable chloramine and ammonia levels coming out of an RO filter. I'm using a 4 stage RO filter only (No DI) and testing finished water quality for chloramine and ammonia, and testing using an API saltwater test kit. Currently reading somewhere...

So I finally got an RODI unit after starting up a new 72gallon. I figured with this much water my trips to big als will have to come to an end I purchased the unit off Amazon. The “Geekpure” unit seems to be working pretty well after some fighting to set it up. I haven’t found a lot online...

I have a 4 stage BRS water saver system that’s around 5-6 years old now. I have it hooked up directly to a water supply with a ball valve on the product line so I can turn it on when I need it. For the wastewater, the line goes outside to a bucket, and just a couple days ago I noticed that the...

Hi, this is my first post on the site... so I hope I'm doing this right. :/ I set my 100gpd RO unit to fill a 75gal container, changed all the filters (except the membrane itself) because it had been sitting unused for quite some time. I tried to flush the membrane as best as I could before...

I’ve been looking to add all three to my RODI system and have been watching some of BRS’s videos to see how it all goes together, but I’m confused. From what I can tell, the pressure switch from Aquatec can only connect to the booster pump or auto flush flow restrictor, not both at the same...

Hi guys! I currently have a 25 gal however in mid August I will be changing to a 120 gallon (450 litres) It will be 5 foot long and the main reason I am upgrading is because I would love to keep larger fish. I have been offered a reverse osmosis system by someone for free, however it has to be...

Hi, two weeks ago I used a new RO unit to fill my aquarium, then switched it off, today I wanted to use it again to do a water change and noticed the resin filter has gone from looking like the one in the online picture (new) to the way mine looks now, is this normal? It’s gone extremely dark...
