interessante.
Ma qualcuno ha avuto squilibri che hanno causato danni?

"During the first 12 months, the calcium reactor was responsible for dosing the coral-building elements. The results were good, but sometimes the water parameters didn’t seem stable enough. That is one of the worst things as far as SPS (small polyped stony) corals’ health is concerned. A few months ago I changed to the Balling method.* Now, three solutions are being dosed via a Grotech TEC III pump. In my opinion, it is very convenient as all we have to do prior to ”the balling method” is measure the water parameters to determine corals’ daily demand for calcium and alkalinity and set up the dosing pumps accordingly. It guarantees 100% stability and, above all, peace of mind. Any possible changes in demand can be corrected quickly and trouble-free. Preparing the Balling solutions is no problem either; I use 29-liter (7.25-gallon) containers, so I can forget about it for a long time."
