BRS Universal Carbon Block

@Bulk Reef Supply
I noticed the new Universal Carbon Blocks look different from the previous version, as shown in the photos. Are these an upgrade in filtration performance, or primarily a design change?

My water supply sometimes contains chloramines, so I’m particularly interested in how the two versions compare for chloramine removal. Could you provide the manufacturer’s specifications or performance data sheets for both, including rated chloramine capacity and the flow rate and test conditions used?

Thank you!

Following. These filters are the backbone of my successful reef, so supplier change is concerning.
