Calcium suppliment blocks?

A long time ago (10+ years..) when I was last in the hobby, I had discovered a calcium suppliment block that seemed to work in my reef. I beleive they were called HBH blocks? Does anyone know if they are still produced or if there is something similar out there?

Well a quick google and I see they're still made. Claim to maintain ph, Ca and add trace elements. I have no experience with them though.

There are a few discussions here on RC regarding these as well. Here

Ah... Yep, looks like general feeling is not to trust them...

They are an uncontrolled form of dosing, so I wouldn't trust them. People do have problems with them.
