reverse osmosis

Hi all, My tap water runs at around 400/450 TDS. No idea what that is, I do know though the water is very soft. So KH is 0 and GH is like 1. My RO System is supposed to be a very good one. It is commercial, made for shops. I don't think you can find it outside of europe, but it is the Blue Pure...

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?

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...
