Single Deionization Canister

I kept getting large amounts of green hairy algae growing on my live rock. I read if I added the DI to my RO system that would help remove some of the components to grow algae. For about $60, BRS had the best deal on all the parts & resin to create a bypass off my RO system. The DI canister is high quality and it took it my TDS down to zero! I needed to update my membrane and my TDS from my RO was high so it used up my resin after 20-30 gals.

Ordered two of these. While waiting watched the installation video and was ready to go. When the units arrived one of them worked exactly as the video said it should. Water pours into the chamber outside the internal cartridge, pools in the bottom, then is forced up through the entire media cartridge. This action leaves a bubble of air trapped at the top of the chamber. This is cool, and shows there is no leak in the seal at the top of the media as if air is prevented from leaving, so is untreated water.

The problem was with number two. As I opened my water valve the entire chamber immediately floods. I can watch the air immediately push into the outgoing water line. Note that there are three inches of water preventing the air from looping through the media via the bottom of the cartridge inside. The only way it is leaving the chamber is by going past the upper seal on the internal cartridge while the water underneath it pushes it up and out. Once this air is gone that allows water to follow and leave the chamber untreated as it didn’t have to pass through 10 inches of resin.

I have a new seal on the way now, after a phone call that was mentally painful. The individual kept repeating that the air inside is okay (I know) and I could purge it out if I wanted to, it took a few attempts to explain that it was self purging this air immediately into the outgoing water line, and without going through the media coloum. This was with a factory packed resin cartridge. Brand new. Aside from the migraine, my experience with BRS is excellent and would not hesitate to order again. (On hold music needs to be better)

TDS at "0" comes ready to roll ...plug-n-play

Excellent products I keep my tds 0

The title says it all.

Nice addition to my four stage thus extending di media replacement times.

Easy to set up, great addition

Hooked this up to my 4 stage 75 gal ro unit. When i shut the system off this container drains to about half full of water?.. is this normal?

One word about this product,, awesome. Customer service connor, great service. Thanks
Brs!!

I used this product to upsize my DI capacity from a top mount to a canister. Worked exactly like I planned. Now I can hold more DI resin and I can watch the color change to know when its exhausted

I upgraded my 4 stage Kent Marine Hi-Si unit and the results are great. I added this DI cartridge onto the end and added an extra carbon filter on in the middle.

This stage, in my case, was a plug-n-play addition to a 6 stage drinking water kit to give me that peace of mind I get knowing I will never go above 0 TDS.

Packed well and ready to go.

My next item on the perfect water wish list is the auto flush valve!
