Okay Hennie I red through those threads and thanks alot again
My pleasure
-can I just continue adjusting my alk and ph with your "koeksoda" method and use those dosages that is prescribed?
Yes, although the dosages would depend on the size of the tank, and on the calcium / alkalinity demand. With no, or only a few, corals you should only need to add quite small quantities. Test the alkalinity, then don't add any buffer, kalk, calcium or anything else for 48 hours. Test the alkalinity again, and that will give you an indication of your tank's alkalinity demand.
-what is the two part additive you talk about that I should do after 4 weeks,
It's actually a 3-part additive, formulated by Dr. Randy Holmes-Farley in the USA. It consists of calcium chloride, koeksoda and a mixture of magnesium chloride and magnesium sulphate (Engelse sout). It is described in An Improved Do-it-Yourself Two-Part Calcium and Alkalinity Supplement System by Randy Holmes-Farley - Reefkeeping.com
-is your alk best nearer to 7 or to 10?
Natural sea water has an alkalinity of about 7. It is better to keep a tank's alkalinity around 8-9, but it's still perfectly OK at 7
-How should I add the bicarbsoda mixture,and how does a dripper work and how much at a time etc
The two (3...) part components are in liquid form, and are just poured into a high-flow area of the sump (preferably), although never at the same time. I don't have time to check now, but if you search the MASApedia you should find more indo. Else just do a search of the forum, using words such as kalk dripper, etc.
