My doser came in today =)

If you already keep params up by say dosing 4 cap fulls of purple up then you know roughly you use 20ml per week so you dose 20 ml spread over 7 days.

I dose anywhere from 180 to 200 ml per day of cal so I spread it out over 20x in a 12hr period, my alk and mg dosed at the same time frame but on the next 12 hr period.

So this is my dosing chart:
10am-10pm Ca 180ml
12am-8am Alk 160ml
11pm-8am Mg 170ml

And as the OP said test every 3 days to make sure everything is bang on for first week, if it is test weekly then BI weekly and so forth.....

I normally just put in 1 cap of purple up whenever I remember to like once every week. What is the optimum cal and alk I should keep in order for best sps growth?

Which seller did you use? I would like to get a back up motor as I have all ready went through my first one about a year ago. Has worked great ever since but it is good to have a back up.

If you are getting into SPS now, I highly suggest switching to a more balanced 2 part dosing system like BRS 2 part, Reef Supplies 2 part or B-Ionic. http://www.reefsupplies.ca/online-store/2-Part-Dosing/ Something along those lines. I don't know what the concentration is of the Purple Up or Seachem products.

You can safely increase Cal by 100 and ALK by 1 Dkh in the span of 24hrs. Don't try to do it in one shot though as it can potentially cause issues. Everytime you dose ALK, you will also increase your ph levels so it is best to dose ALK during lights off when ph is at its lowest point.

To figure out what your tank is using, you need to test once. Record your results and then test again at the same time the following day or 3 days even if you want more accurate results and then just divide by 3 and that is your daily consumption. Then use the BRS calculator and figure out how much you need to dose everyday. There will be a lot of testing for the first week or so and tweaks until you get it just right.

Gonna be picking up some soda ash and calcium
Chloride from KpG007 soon. Hope that will be better since purple up has to be shaken up real good before each use and that's not really practical for dosing. Still don't understand why adding the alk n cal didn't show a difference in yesterday's testing. Cal dropped 30pm by today. Is that normal?
