  1. Whenever I stop using GFO for awhile, I get algae problems. Once phosphates go high in a tank, they seem to get attached to live rock and sand chemically. You need to keep running GFO to remove the phosphate that leeches into the water once the concentration of phosphate in the water is lowered. At some point, you will get the phosphates down and then you can keep them down using less GFO.

  2. When you add water to the salt mix, the alkalinity and calcium in the resulting water are in such high concentration that they combine together and precipitate out as calcium carbonate. There are probably other combinations of ions that will also combine in such a high concentration. We want the corals to do the combining to form their skeleton.
