di resin

Brand New BRS Deluxe DI Canisters with Dual TDS meter and media installed. Never used. Bought ~ 2 months ago. Can't return to BRS because I tossed out the original packaging. Has never seen water. Shipping from 46373 or willing to meet local.

“Why am I burning through my DI?” is a question that we get asked often. Read our latest blog on why this may be happening and how to fix it.

Has anyone tried to recharge or successfully recharged deionization resin? I found this interesting video on how to do it. You need two things you most likely already have: RO/DI water TDS meter. Two dangerous solutions you don't want to leave around children: 5% hydrochloric acid solution...

I have a 5 stage rodi system and it's currently letting 8 tds through, super high, I know. But my resin looks unevenly worn. Is there a problem with my system or is this when I would normally need to change it? I thought it should all change color before needing a replacement.

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...

Hello all, I am having an extremely frustrating issue with my RODI system. I will provide as much detail as I can for the context of my issue, but hopefully someone could help me determine what my true issue is on my system or have any tips/suggestions to troubleshoot. I am only about a year...

So I have a local friend that runs cation, then anion, then two mixed bed resins (all color changing). He almost never runs out of cation but does run through anion. Being that I’m using the same city water supply, is there a reason that I can just skip the cation and run two anions instead? I’m...

I've been struggling with red cyano again; and my corals haven't been happy for about a month. The issue I found is that my RODI membrane is putting our 36 TDS and the DI resin is only polishing it down to 8 TDS. I'm not sure how I missed this. So I've been cleaning out the cyano with water...

Hello everyone, I've been having issues with ammonium readings in fresh made ro/di water lately. I'm using this ro setup from BRS and swapped all the canisters last week, however the problem still persisted. So I upgraded the carbon block to this and took another reading again no change. Here is...

Hey all, though I’m not a reefer yet, I’ve been having fun using stuff from the reefing hobby but on my freshwater planted tank. First post! Anyways I had a dumb question around RO/DI water and the DI resin. After reading a couple of posts, I came across this notion of “food grade” DI resin as...

Is it normal for the water to not go up all the way on the Resin cartridge? Mine seems to do that and anyway how to fix it?

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, 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...

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 just can't get this algae or cyano bloom to completely go away. I thought it was cyano, but it doesn't create "sheets" like typical cyano pictures. I let it go for a week without blowing it off rocks and the back wall and then cleaned the tank thoroughly. Ive been doing 20% water...
