Hospice has been called in now and the Oncologist team told him he has about 2 months left. I wish I had better news, but thanks for asking just the same.
I have heard of many people having success with raising their calcium against Bryopsis, but it seemed to be one product in particular that worked the best. I think it was Kent Tech-M and it was actually a side effect of dosing with it. I know there is at least 1 thread on here about it if not more, so you may want to do a search on that.
