Well it looks like IO mixed with the Reef Salts gives me an acceptable range of calcium. I ended up bump the alk up a bit with baked baking soda to be in balance with the calc and adjusted the mag. But all of the tanks have responded well and I haven't seen any more precipitation in the holding tank.
None of the tanks have enough carbonate alkalinity. Not sure what I have been using to get the borate so high (even higher than the Reef Salt has). I'll be retesting all the tanks today and see what levels I get now. I have already noticed a good change in the pH levels on the 125. I am getting less fluctuation in pH between night and day.
