Ok, I have already split 10 pounds out. Getting ready to do another
bucket or three (it comes in 5 lb buckets). I will mix in the boric
acid before I ship it out. I'm splitting into 1 lb (nominal) bags.
The cost including shipping in the US for each pound is $12. This
will give you trace minerals for quite a while, unless you have a
large high light tank or lots of tanks. Then you will only have a
supply for a good amount of time. If interested email
