tds

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...

What is everyone here using to test the TDS of their RO/DI? Any tips or experiences concerning the reliability of cheap TDS pens? Would you trust a cheap HM Digital TDS-3 Handheld TDS Meter? Plenty of positive reviews, but a reviewer pointed out: The Hanna Pure Water Tester looks like a better...

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...

I'm new to reefing and saltwater in general, and I now have a pretty large algae bloom. I read somewhere it can be caused by something in the water if it hasn't been filtered properly, or that the presence of it also means the tank has finished cycling. Regardless, this led to me testing the TDS...

Hello, I have recently moved to a larger tank and larger holding containers and I have found that I need to replace my DI resin just about every week or else my TDS starts creeping up, which raises my ALK in my tank via ATO. I do have well water, so its gross. At the RODI unit, it goes in at...

I’ve recently moved to Colorado from Florida. I’ve noticed that the tap water here is cold enough someone LITERALLY does not need ice lol. In fact when the rodi was running at night to fill 100 g system (Total water volume). There was condensation on the unit. At just a hair under 80 psi and...

Is it safe to use rodi water that has 3 tds? My rodi unit needs new filters but i have about 45gallons of rodi water that has 3tds i feel bad dumping it but dont want to use it if it'll cause problems.

I was making RODI water today and testing it as it comes out of the 4 stage RODI filter. It was reading ~160 in and 0 TDS out. I then put the fresh RODI water into my 20 gallon saltwater mixing tub which is a food grade Sterilite storage container. Within minutes I tested the water and it...

Would 0 TDS RODI water mean that tin is not present, or could tin not even show up on TDS meter?
