Reef Safe Brute?

[Kdocimo90]

Was wondering if the black brute containers are reef safe.

They are listed as certified to NSF Standard #21

I don't know about the black brute containers... have used the gray ones with no issues, but now use these that I got at tractor supply.

I use those brute containers with no problem. That said I would DEFINATELY RINSE THEM OUT really really well first though. I once had my system crash (luckily saved almost everything) because there was residual soap in a brand new brute I was using.
