I find your tangent after rolling the pail down the stairs around the house i always found very low alk readings from the few pails of h2 ocean i used. I always keep 90 gallons or so of water around for emergencies and with the h2 ocean i found it leaves some nasty stuff in the tub along with other salts also. With the Rb there is nothing even after 3 weeks. Another reason i changed is the crappy plastic handle on the pails or h2 ocean almost broke me toes a few times. When you read on zeovit.com some people say mg bang on some see it as high as 1800 so it seems weird.
