the best di resin

Weyou · Apr 15, 2020

What do you guys and girls thinking is the best in the market today.
i use aqua forest di resin and thinking to switch to triton di resin, what do you think about best di resin in the market today has to offer?

Following. I burn through a cartridge refill after about 60 gallons of useable water (BRS color changing). Have a bulk order of non-color changing resin coming today the reviews say that it lasts longer. Will let you know.

Spectrapure... I’m using their high capacity MaxCap and a high capacity SilicaBuster DI cartridges. I’ve been on the same 2 cartridges for 2 years and both are still producing 0 TDS water as measured by my dual inline TDS meter used on the DI stage of my system. I make about 20 gallons a week and my post RO membrane reading is 1-2 TDS.

How would one evaluate the ‘best’ resin I wonder LOL.

Longest lasting... at least for my water situation.

Also, I do enjoy not having to fill up and pack bulk resin into canisters. I used to make such a mess of it! :mad:

I still make a mess of it. That's unreal the spectrapure. I used to go about 6 months on resin from the old school company The Filter Guys. I dont think they're in business now.

I will say that I have pretty good source water at 75 TDS. My RO membrane is 2-3 years old now and producing 1-2 TDS. When it was new, it was reading 0 TDS post membrane. That’s one of the reasons my Spectrapure DI cartridges have lasted so long as post RO membrane TDS has been very low.

If you have high TDS source water and higher post RO membrane TDS readings, your DI resin will deplete much faster.

Wow that is a long time for resins to last

Going on 3 years with my Spectrapure DI resins too. Water in is 100 TDS.

I like the nuclear grade anionic and cationic from brs. I found that my RO water really only gets treated by the anionic crystals, so, I just run a small cationic (which never gets depleated) and a huge anionic. Cut my DI costs in half.

cvysochin · May 23, 2021

BRS separate anion / cation hands down. Have tried many others, marine depot, spectrapure, etc, etc, and they aren't even close. Like the poster above, our water has high co2 and burns through anion quickly. A regular mixed bed cartridge used to last 50 gallons. And now, one cartridge of anion lasts over 300 gallons. No interest in degassing, easier and cheaper just to keep tossing more anion at it.

The best di resin is the resin that is packed 100% into it's canister without any air pockets.

Pro-tip. After you think your di resin is filled I can guarantee it isn't. Improperly packed di resin leads to channeling. After I refill di resin I make sure to recheck the canister after running several water cycles. Sure enough there's room for more di resin.

That is nuts.. how much water has passed through the di resins... 3 years.. ????

Everyone here who has run tanks for several years must have gotten sub par stuff every once in a while. I order from premium aquatics and every darn time I try to go elsewhere it does not last as long.

So basically through experience. I know some sources are not as good as others.

I'm not sure what you mean by that. I would be very lucky to get 30 frags at once!

Any tips on packing the cartridge. I fill half way. Then use Locke a smaller bottle and film and do it again. And yep sometimes not compact enough.

Hundreds and hundreds of gallons

I get 6-8 tds out of my spectrapure dws90. That’s before the di resin. May be why your di lasts so long, the rest of the system pulls more than its weight

I'll run the new cartridge for awhile and then check it to see if I need to top it off with more di resin.

Would love to see what TDS we have coming out of and after the ro membranes and then how many gallons the resins clean to zero TDS before becoming exhausted. Is two hundred to much to expect to pull 3 TDS to zero for example.

Same. High CO2.

I run Anion, cation, then the mixed bed.
