Aloha David, a friend has given me a simple way to do it.
1st. get a couple of cannining jars fill with water to an inch from top.
2nd. get in my case some salt pellets from water softener salt bag about four will do. Add to water.
3rd. add as much bs eggs as needed.
4th. add aeration.
In about 12 to 18 hrs you should have some bbs. The second jar is for second batch for next day. I always try to think ahead and this way you dont run out of bbs and you always have a fresh batch.
I would post pics but have no digi cam. it is on my get it bad list. ;D
I am sure there other ways but this is pretty easy for me.
Aloha for now, Ike & Anne ;D
