Aquatic Life DI Color Changing Mixed Bed Resin Cartridge

Aquatic Life DI Color Changing Mixed Bed Resin Cartridge

Q: There are 2 sizes of this product on a different website. Can anyone verify if this is the 21 or 31 cubic in. version?

I am unsure what u mean by 21/31 cubic in, I bought this cartilage for my 100 gallon per day aquatic life ro filter and have since put out hundreds of gallons of 0ppm water, it has started changing color but still has long way to go, without the di cartilage the filter puts out 15ppms with the intake water being just under 200ppm

Q: How often do i need to replace this cartridge?

It's refillable. Top cap is removable and replacement resin may be purchased much cheaper than a cartridge. Depends on amount of water passed through it as well as how contaminated it may be.

Q: Will I need to purchase any tubing or any other additional pieces aside from the RO Buddie itself?

Yes you will need extra tubing for the r/o buddie. I just got my r/o buddy a few days ago. Make sure you cut the tubing clean. Otherwise it will leak. first 10 gallons have been 0 ppm. And my saltwater tank looks amazing.

Q: My cartridge does not remotely look green, it's more like a shimmering black, purple, and blue. Anyone else had that problem?

Is it blue when new or it turned blue? Mine is green. I think if it's blue it's used.
