Based on BRS and Spectrapure's media reactors looking identical (minus some minor differences on the stickers), as well, the fact that pretty much every other major online aquarium retailer stopped carrying Spectrapure after BRS bought out Marine Depot (so assuming they must have some kind of exclusivity/non-compete contract...aka monopoly lol), I suspect that some or all of BRS's RO/DI materials come from Spectrapure, but I don't have any other info to 100% confirm if they are identical or even the same grade. Given that, I will continue buying Spectrapure, even if more expensive, because they are the established leaders of the RO/DI industry.
I did not find them to be identical at all and why I switched.
Then if attempting to recharge their mix resin, ya find out it is a hot mess and ratio is off.
Spectrapure makes their stuff in house and BRS probably buys from Temu (jokes but probably somewhere bulk and cheap).
