Most sucessfull and most beautifull sps tank i know uses 2 part solution.2 part is the most comfortable way to keep Ca and alk stable because by using a kalk stirrer or a CO2 Calcium reactor you will still need to adjust especially alk from time to time.In an old aquarium with rocks that arent leaching phosphates it doent matter if you use kalkstirrer or CO2 reactor or 2 part ,the result will be the same .But in a new tank the higher ph of the kalk and the kalk itself will make a difference with kalk being the fastest to stop the phosphate leaching rocks from all the 3 different techniques to add Ca and alk.
And now you are talking about the best way to supplement Ca and Alkalinity. Plus what I posted about in Randy's article about pH benifits of limewater additions.
Let me remind you and keep on track here.
Just read the thread title you started.
Calcium vs. GFO binding phosphates
Your argument is that calcium hydroxide is more efficient then GFO and at least on par with LaCl3 at reducing phosphates in our saltwater aquariums.
Please, if you can back that up do so. If you can not then please say you can not. It really is that simple.
