LiquaGen 2.4 Pounds - Aquarium Reef Color Changing Deionization Resin (RODI) for 0 TDS/PPM Water - MBD - 30 | Deionized Reverse Osmosis Filter Media for Fish Tank, Reef Tank & Other Aquatic Life

2.3lbs is close enough, but the right way to do business is it should be a little more then the advertised weight to account for the packaging bag. oh well. it works.

This DI resin is mediocre. I thought I would try it to save some money from higher priced stuff. What I found was there is not money savings because you have to change it out more often. Color change happens quickly. I only use that as an indicator I should start checking the TDS readings. And sure enough TDS is reading higher than 0-2ppm. I even went as far to take a sample to a water store just to make sure my TDS reader was calibrated correctly and they got the same reading.If you on a budget buy it. If you are concerned more for longevity go with a more reputable place like Bulk Reef Supply or Spectrapure.I DID NOT receive this at a discount in exchange for a review.

Well, it arrived and the packing was just a bit odd. Being in a zip loc bag was strange but it made it easier to put in the filter and store. Using this stuff in my water system that I use for my reef tank. Glad for the color change. Will update later after I see how many gallons I get after thr ro unit.

I purchased this for my RODI filter for my reef tank. So far it works great. will probably go this round again when it runs out. Thanks A bunch

Packaging makes it easy to refill the DI filter

This is what I needed for my system and it seems to be working great. Will order again.

Changed color like it was supposed to. I only got 150 gallons of on a 10" filter.
