tds

I got a BRS 4-stage RO/DI unit set-up last night. Let it run for a while to "flush out" whatever it needs to flush. But checking the TDS readings now 12+ hrs later, it reads between 2 and 4 ppm on the output water. So not the ideal 0. Anybody got any ideas? Is 2-4 still acceptable (right now it...

Hello! This is my first post in the forum and instead of creating a dedicated thread I prefer to directly ask the question, I hope this is ok :) I've been lurking for some time reading @AZDesertRat and other interesting posts. Great information here, thank you so much for sharing. I'm running a...

Hi I would really appreciate some input. My well water is horrible and I just updated the whole home water filtration system. It first gets injected with hydrogen peroxide. Then it goes to a 50 micron sediment filter then it goes into my iron removal tank and lastly through my water softener...

Just got my Bulk reef Supply 6 stage RODI on Friday , When using it my TDS ( In ) Reads 12 or a tad higher I forget what # , But When coming out 0 ( as I want it to be ) I thought between the sediment filter , 2x carbon block and Membrane that is like 96-99% rejection rating Would get me closer...

Hello! Just a quick question… I like to always have some RODI water on hand for emergencies and to make water changes faster. I always have it sitting at 0 TDS and check it before and after. When I went to do a water change today the RODI water which had sat for a few weeks was 41 TDS. So I...

Today I decided to test the TDS coming from my 4 stage RO buddie and the TDS is reading 25PPM, I’m using a HM Digital COM-80 to measure the TDS (it might need recalibration?) the source water is testing at 167PPM, my corals all look healthy? The RODI unit is approximately 7 months old, I’m...

I am hoping that someone here might be familiar with the Aqua Medic Platinum Line Plus RO system as I am having some issues with its ability to actually filter my water. After replacing the membrane and resin, and flushing for two hours, my TDS is flashing 99. The system is one I took over...

I live in NYC and the TDS has always been very low, around 30, but my pressure was never great. I wasn't using a booster pump so I would get maybe 40psi at the membrane and my 90gpd unit would make maybe only 50gpd, but I would go years without changing a single filter. About two months ago the...

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...

Hello, I just added the brs water save upgrade, a booster pump, and I changed out my di resin and sediment filters on my brs 75gpd 4 stage unit. I used the unit yesterday and the water was coming out at 0 tds and I made a big batch of water. Now today the water is coming out at 3 tds. I’m not...

Hello, my brs 4 stage 75gpd rodi unit started making water that had a tds of 2 ppm last week. I've had the unit for 6 months now and I'm assuming it's time to change out the filters. I changed the di resin today and it's still producing water with a tds of 1 ppm. I’m pretty sure I packed it in...

Hello, I recently moved to south florida and bought a house. I have a well in the back yard for the sprinklers. Because it’s a well I don’t pay for the water. I purchased a TDS meter. I checked my tap water and it’s reading 120. I went outside and tested the well water and it’s 150. I’m...

Hey all! I have had my tank up an running for almost a year now and for the past few months I have had a bad case of what I think to be diatoms or dinos. Both my phosphates and nitrates are a little over 0 (API test, but it's the best I have right now). I recently acquired a TDS meter and the...

Hey all! I have for sale two pressure gauges and a TDS monitor for your RODI filter as follows: HM Digital TRM-1 Triple Inline TDS Meter brand new in package - $25 Sold! The Water Filter Men air filled pressure gauge, brand new in package - $15 Malida gel filled pressure gauge, new open box...

Good evening, I was wondering if anyone has experienced false readings with an inline Triple TDS meter. If so, is there a way to get it to read the TDS correctly? I recently purchased a new Triple TDS meter along with new filters from BRS. I removed all the old filters, installed and flushed the...

After 3 months of use of my 75 GPh 6 stage drinking and reef Rodi system I’ve installed a flush valve from BRS . When I flush the system I should not produce any water , but I produce anyway water and all the TDS crap goes into my drinking water tank or in the DI resin. If I flush or not the...

Hallo!! I have been trying to see if anyone has done this, but I cannot find anything. So for my ATO container, I have a float valve and it’s connected directly to my RoDi. The reason is because I don’t have a lot of space for a big container. My wife is always home so I don’t worry too much if...

So I have my RODI unit connected to a water collection tank that's never seen tap water, and was wondering if I could plumb the wastewater line of my RODI unit to a pond? The TDS of the waste water is 006 to 007 ppm, the TDS of the rain water coming out of the tank about the same. The pond is a...

So I have a mystery I cannot explain with RODI (BRS unit). My source water is less than or around 300 TDS, and the RO membrane (99% rejection rated dow) takes it down to around 6-8 before going into DI resin. After DI resin it comes down to 1 TDS. The process ate up DI resin fast compared to...

So in a continued effort to understand what's in my City Water and what poses a potential risk and would need to be filtered and treated for a tank (Fish Only With Inverts), I found my local plant water quality report, and am curious from others who have more knowledge than me, how good (or bad)...

So i have been getting R/O from my LFS that i work at and 4 of my zoa frags have not been opening up. I bought them 2 weeks ago and my latest theory is that my water im using is not 0 TDS. I'm looking into getting a unit from BRS but idk how hard my water is. I know in Ventura its at 900 TDS. I...

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...

I have two brute trash cans that I use for my rodi storage and mixing station. I’m gonna call the clean rodi water storage can Can A, and the other one I’ll call can B which I used to use to make the saltwater mix. Normally I use can A just to store and heat the new rodi water and can B to make...
