Review on Seachem Purigen Liters Model 168 by Carmen Winters

This product works as intended. However, the container has a terrible lid design that unscrews during transit. The first order was damaged in transit and could not be delivered. I had to replace, and all the little balls in the box crumbled. It was a nightmare to use the hopper + shovel and put the balls back in the container, maybe 5% of the balls got lost on the floor or got stuck between the sheets of cardboard. Highly recommend Revain or the manufacturer to glue the lid onto the container or create a better design lid. Alternatively, customers can opt for the smaller 100ml packs for peace of mind.
