LiquaGen Bulk Pack Aquarium Reef Color Changing Deionization Resin Bag (RODI) for 0 TDS/PPM Wate | Deionized Reverse Osmosis Filter Media for Fish Tank, Reef Tank & Other Aquatic Life (18 oz)

I use this product for my reef tanks RO system. I started getting it on Amazon and it is faster and I don't have to drive to the aquatics store.

product came in a zip lock bag. there was moisture in the the bag resin started turn color before i was ready to use. i guess if your going to use it as soon as it arrives go for it. i always like to have one around in case of emergency.

I like have fast it showed up but done less then 50 gal with my 8 stage ro unit and it’s already bad ro unit it’s self is 13 ppm before the resin now with the resin 2 ppm is what I was getting out of it less then 2 days of use

This resin is great - it works perfectly in my reverse osmosis system to help purify the water I use in my salt water fish tank. I will definitely keep this on my list of products to keep on hand.

This will save me a bundle its easy to get out and fill canister. Very improtant medium in my ro/di system to make 0 tds water for my marine tank.

Excellent material. Very fast shipping
