Hi STarry,

I have the dreaded BSP invasion took the main rock that was covered and boiled it however not an optionin main tank. I have researched last couple of day the safeguard product with that chemical in it. Can you tell me exactly how much you dosed/how many times you did it and any other pointers. I just did the kalc paste on as much as I can see but I know its in the back of the rocks where I cannot see it. My thought was to try to get rid of as much of this stuff via other means first then do a final with safeguard to avoid as much reaction as I can

thanks
