Sealabs No 28 Mineral Blocks Availablity?
 

Was wondering if anyone uses this stuff still called Sealabs no 28 Mineral blocks... I don't have a tank big enough to justify a calcium reactor nor do I want to set up a doser w/ kalkwasser so this might be an option to keep my calcium in the 400 range. Anyone in canada carry it or only in the USA?

thanx
