Review on 🐠 Seachem Matrix: Ultra-Effective Aquarium Filter Media, 4 L / 1 gal. by Melissa Sanchez

I received this product to remove nitrates from my aquarium, after adding a few scoops I found that half of the medium was powder. Because of this, I can't use half of this pale color. I hope every seller sees this post and wants to let me know! The medium works fine, but I bought 4 liters of medium, not 2 liters of medium and 2 liters of medium powder. Media powder cannot be added to my aquarium filter and I would like a refund for the remaining 2 liters or half my money.
