Thanks huys. I will endeavor to find an Mg test kit. Ca is up to 300 this morning, seeing great white borders to my coraline and my green star has at least 6 new heads this morning. It hasn't grown at all since transplanting to the new tank.
I have been using the top up solution that I made and will keep using it until my readings are in the 425-475 range. Had some precip in the bottom of the top up container. I thought that was pretty normal. Have been monitoring Alk and it has not moved.
Yippee.
Mike.
P.S. in the 21st century they have computers... under the accessories there is a calculator function. It is much smaller than the abacus or the solar powered... if you ignore the tower/monitor/printer/scanner/computer desk/etc. involved with it. On second thought... does anyone have a spare abacus lying around.
