What RO/DI unit are you currently using in 2019?

[lolgranny]

Everyone needs to get on board with the non mixed di resin. I’ve saved so much $ since I use them separately. I have 3 di containers. 1st caiton, 2nd anion, 3rd mixed bed. I almost never have to change the mixed bed anymore. The anion goes quickly, but then again I have a 700g system that gets 60g changes every week or 2 lately.

No-one buys demineralised water from the hardware store?

BRS 6-stage. Very good quality, makes like 125ga/day. Reasonable price, and it can be moved to various locations easily. If I were to buy a handful of the in-line under sink fittings and in-line cutoffs, I could even loan it to friends. But I don't have any local reef tank friends :-( yet...

A vertex Puratek 3 stage, been using it a few years now without issue. Chose it as it was the least expensive one at my local store.

@LukeWolf What is the TDS coming out of your well? Mine is very low but I have yet to send it in for ICP analysis just to find out exactly whats in it. Right now I am running through a RO/DI but have thought about skipping the RO and going just through DI.

I dont know what my TDS from well is. I have not tested it. only thing I have tested in it is to make sure it was safe for drinking (so chemicals, iron I think, ph, kh, and other things)

BRS 4 stage with extra expansion to 150GPD.

I started with a API Tap Water Purifier, then added an AquaFX bare bones to that which at the time was an RO and sediment filter combo. My setup is now made up a carbon block, 50 gpd RO/DI.

Spectrapure MaxCap 90 with booster pump. Also installed a 1 micron sediment filter pre booster.

BRS 4 stage RO/DI with the pro upgrade dual TDS meter. I love this unit, and I am fortunate enough to have “good” tap water. Relatively low TDS and no chloramines....

I use the BRS 6 stage water saver plus 150gpd.

I am on San Antonio city water which is pretty rough stuff in my opinion. However, I wasn't born and raised here so I am not used to it. It'll stain fixtures in a short period of time.

So, I have a Jason's whole house water softener for the house. The BRS unit is fed the softened water.

I also use the separate anion/cation media and only one ever gets used up (forget which right off) and the other looks like the day I put it in.

For those that may be curious below is a link to the water softener:

I'm currently using a BRS 7 stage 150gpd water saver unit. I absolutely love it

I use a 16 year old AquaFX 5-stage Mako RO/DI unit. Still going strong.

I built my own by buying the parts separately from BRS. There's not much to making your own with all the bells and whistles and stringing some tubing together. Only thing I took from a friend was the bracket.

Though I've been looking at the Puratek unit. Seems like great value for what you get.

I've seen a lot of really tempting options on Amazon but I'm just not there yet

Ro buddie 3 years strong.

Bought an aquatic life twist on unit because it does great delivery and takes up little space. At last minute got a good deal on marine Depot 4 stage unit.
Now reading on the twist on unit and almost tempted to use it. Way easy to use, change cartridges which is cheaper than resin

I use a 16 year old AquaFX 5-stage Mako RO/DI unit. Still going strong.

My AquaFX is only 15 years old but I have added a BRS Monster to take care of the Chloramines and a separate DI canister. Other than that all the O rings and containers are original.
