Well worth it! By Scott on 4/12/2017

I have a non BRS ro/di setup and was running a 100gpd membrane, watching 4 gallons go down the drain to the 1 gallon I was making just seemed such a waste. I am fortunate to have high water pressure so a booster pump was not needed. Installation was easy and now I am close to a 1.5:1 ratio for waste water to ro/di water.

Bar far the best RO upgrade!! By Skynyrd Fish on 3/16/2017

I sat on this for a while before I installed it. What a mistake. It is easy to install and doubles your output. If you don't have one of these you are wasting water and $$. After 25 years of reefing it is by far one of my favorite upgrades as it did exactly what it says it will do.

I should have purchased this a long time ago. I thought I had it ok with my 100GPD, which only produced like 75 per day, I finally decided to make the switch and see if I could produce more efficiently. I switched out all of my filters and also my old membrane and added a Dual DI Canister. HOLY COW!!!, I am now producing 240gpd. I can fill up 10gal in 1hr. Its amazing! I am so glad I did this purchase and wish I would have done it sooner!!!!!

It cut my waste water from 2.5 to 1 to 1 to 1. On same note nearly doubled the output and time.

Its pretty much a no brainer. You get double the water output and it cuts the waste water in half.

I have had my eyes on this upgrade for a while now, but it was time to replace my RODI filter media so I finally purchased this kit. Watched a youtube video to figure out how to connect everything and the difference in water production is outstanding. If you have a 75gpd kit and a booster pump, purchase this upgrade immediately. You will not be disappointed.
Half the wastewater with barely any TDS increase By TS on 7/10/2016

My TDS is about 180-200 and I'm using 65 PSI. With this upgrade I get 4 TDS on membrane one and 9 TDS on membrane two. That's without using any DI canisters (which seem completely unnecessary with a TDS that low - at least for my freshwater aquariums). I've just rewired the extra canister as a second carbon block to keep the membranes extra safe.
One thing I learned the hard way - whenever you're shoving membranes in or out of the housings, apply silicone grease to the brine seal (the black rubber around the top of the membranes) or you may end up tearing or deforming it. I spent several weeks scouring the internet trying to figure out why my TDS was suddenly coming out around 140, replacing almost every part of the system, before realizing I just needed to grease a stretched brine seal.
RO/DI upgrade By kingspeed on 4/30/2016

Added this to my existing 75GPD system, I can make 10 gallons of water an hour with only 5 gallons of waste water. It use to be the other way around and it would take 3 hours to make 10 gallons.
