Good morning! I was curious if anyone else has experienced this type of leak. I changed out my filters in my 4 stage BRS RO system and now the top of the pressure gauge is leaking. I have never had this issue before, and the water pressure going in is the same as it was prior to the filter...

I've been making my own DI water for about 5 years. Source water was always very high quality with low TDS and I've never needed to replace anything. Granted, the carbon/GAC is probably long used up, but the sediment filter was still bright white, pre-membrane pressure was 45-50 with just a...

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 have a 20 gallon reef tank with me at college. My dorm is an apartment style dorm with a bathroom and a kitchen that I share with my roommates. So far, I've been buying all my salt and top off water from my LFS. This isn't very cost effective, and their alkalinity for their salt water is...

I have the spectapure 90 gal RO unit. I also have the Aquatic Life Smart Buddy. I'm confused on connecting these 2 units together. Does anyone have this? Could you give me some tips or possibly a diagram/schematic on setting this up?

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...

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 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...
