Anybody know if Resintech MBD-15 DI resin would be good for refilling our DI cartridges?
I didn't realize there were so many different DI resins available on the market. and I know absolutely nothing about any of them. I tried finding a local source for DI resin and I think I did, but they sold a bunch of different resins, way more than I anticipated. They actually specialize in building large commercial filtration systems for like semi-conductor chip manufacturers, etc.. and other businesses that need ultra-pure water. They were NOT a bunch of reefers, I can tell you that. They didn't really have anything aquarium related and the room full of filtration engineers seemed to be thrown for a loop when I asked what DI resin they recommended for filtering water for my saltwater reef tank. lol. I got back a bunch of blank stares and puzzled looks and then they all seemed to settle on and recommend the MBD-15 resin for mixed bed use.
one guy said the MBD-15 was a step up from the standard resin and is what he recommended anytime someone mentioned an aquarium....
after doing some digging, it appears that MBD-30 resin is what I've mostly used in the past. The DI cartridges that I've purchased off
Amazon said they were color changing MBD-30 nuclear grade.
Seems MBD-30 is the most common (?) mixed bed resin in the reefing world, but I'm not finding much info out there on the MBD-15 variety that my local filtration company recommended.
just looking at the spec sheets for MBD-15 vs 30, it would appear that they are very similar, with the MBD-15 having maybe 10% higher capacity (?) than the MBD-30 from what I can tell, but other than that, I don't see a whole lot of difference between them.
MBD-30
>0.3 meq/mL
treats 93,195 gallons of 2 TDS water
treats 1864 gallons of 100 TDS water
treats 186 gallons of 1000 TDS water
MBD-15
0.55 meq/mL
treats 102,515 gallons of 2 TDS water
treats 2050 gallons of 100 TDS water
treats 205 gallons of 1000 TDS water
So looks like the MBD-15 resin can filter approx 10% more than MBD-30 before being exhausted.
I typically get 2-3 TDS out of my RO membrane, going into my DI stage, so either option should last me a good long while.
Was just hoping somebody who knows more about this than me can tell me this MBD-15 resin is safe to use and won't kill my fish. lol.
