Review on AquaFX Leaders Reverse Osmosis Deionization by Glen Sprout

Have ordered this several times and the DI resin is great and lasts a long time. It was delivered insanely fast and I trust the AquaFX brand and use it with my Barracuda for my aquariums. I gave it 4 stars because the DI resin wasn't packed tight enough both times I ordered it. There is always some space at the top and when you shake it there is movement and you can hear it shaking. I'm not sure if it's supposed to be that way, but my impression is that it should be packed as tightly as possible to avoid channeling. So I had to fix it myself by going in, tapping it on the counter and putting some of my waste resin on the bottom to make it fuller and denser (so she said). definitely. If anyone at AquaFX is reading this, please box them up so I don't have to do this extra work. I did not. Maybe next time I'll just buy the resin in a bag and bottle it myself. Otherwise an excellent product.
