BRS Universal Carbon Block

[ryshark]

@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.

Same. The carbon block itself of the new version appears to be substantially smaller.

Does it have the ratings like they used to? the former iteration was rated for 3500 gallons chlorine at .5 GPM, considerably better than competing models @2500g.

Yeah, I think the paper label is the same. I have it shown in the pictures.

I just saw that @Battlecorals thread in this forum from over a month ago has no replies from @Bulk Reef Supply so we’ll be lucky to get an answer here.

label says 2,000 gallons chloramines, while BRS website lists 3,500 at 0.5 GPM in the description? Did the old label say 3500?

Screen grab from one of their comparison videos:

I can’t believe BRS would change out such a massively popular product and not put any information out on what changed and what didn’t. @Bulk Reef Supply this is very concerning. I know without the info we need, I’ll be looking elsewhere for replacements

Has anyone emailed them? This new filter looks identical to the Matrikx CTO Plus (which is not rated for chloramines). the Matrikx Chloraguard rated better for chloramines than the BRS universal, but it’s also 50% expensive.
