Hmmm 13% just sticks in my head for some reason.
I also remember them having dosing pumps on sale for $50 and 1.5 lbs of color changing DI Resin for $40.
BRS is a solid company, they have grown very quickly over the last 5 years or so.
I believe they were the first to revolutionize the industry by teaching basic aquarium knowledge on their YouTube channel.
Which gave them another vehicle to market their proprietary quality products, smart.
