Osteoclast,
Thanks for the compliments! Tangs are definitely my favorite fish. I love getting them small and watching them grow. Both my Lopezi and Vlamingi Tangs are getting huge!
I am real happy to share my Apex programs for my Vortechs or any of my equipment. I've actually been debating about getting two more MP40's to create additional flow on an intermittent basis. I enjoy sitting in front of the tank and creating different flow patterns.
With regards to my dosing... the plane truth is I don't know!!!
I purchase from my LFS the Calcium, Alkalinity and Magnesium formulas (I believe they purchase the powder in bulk from BRS), pour the powder/ingredients into 5 gallon drums, add RO water, mix and viola! Because I dose hourly, I use a mixture that is 150% - 170% of the normal concentration for Calcium and Alkalinity. Every month - six weeks when I replace the solution, I have to spend a 5 days or so adjusting my dosing levels. I use the BRS Drew's Doser Pumps, which are supposed to dose +/- 1.6 ml per minute (i'd be surprised if they do 1 ml per minute). Each hour I have my Calcium set for 11 minutes, my Alkalinity set for 13 minutes and my Magnesium set to dose for 4 minutes. I just lowered everything slightly...My Calcium is running at 450, Alkalinity is at 12 (I like it to be at 11) and Magnesium is around 1,200.
I keep my solutions constantly stirring. All my solutions are in 5 gallon water jugs and I have little/nano power heads residing in the bottom of each jug.
I hope this helps....
