Do you guys dose mag, cal, and alk if you just plan on keeping zoas, lps, and shrooms?

Yes, If the big-3 testing calls for it.Do you guys dose mag, cal, and alk if you just plan on keeping zoas, lps, and shrooms?
+1...The testing should be your guide. Salifert test kits run about $10-$15 each, meaning you can get carbonate, calcium and magnesium test kits for around $40. Once you know how to use the Salifert kits, testing is very quick and painless. I can test the big three in less than 15 minutes with ease. If you know your test results and one of the values is outside of the range of "normal", then it's very easy to adjust. But knowing is the first step
Whether you need to supplement or not, I would still advise regular testing and staying in tune with your water chemistry. No matter what type of reef tank you're maintaining, I don't think there's a downside to knowing what's in your water and how your water changes over time.

It does not mean that your corals are not taking in cal and alk ions at the same rate. Calcium is higher buffered in seawater than alk.Well I guess maybe I'm just a little confused. I started testing 2 weeks ago using salifert test kits except for calcium. For ca I have an API test kit. My Params were cal -400, alk-9.2, mag 1200. My goal was: cal-400, alk-10, and mag 1250. After the 3rd day of getting same test results cal-460, alk-9.2, mag-1270 I started dosing brs alk 2-part 26ml I believe to get all of my Params where I wanted them. After the first week my Params were cal-460, alk-10, and mag-1270. Now, I'm at the 2 week straight mark and my Params are all still the same besides the daily dose of brs 2-part alk that I'm doing. Does this mean that my tank is only consuming alk? Do I not need to worry about dosing mag and calcium? I never dosed any mag or cal during this time. The cal and mag both rose without dosing anything besides the alk part.

lol,All test kits have a margin for error. Myself ,I test twice quite often.

Just took my harlequin shrimp (pair) back to them.Yes I do! Actually, I'm planning a trip there tomorrow.

Using these guys right now.Any recommendations?
If you read threw the S-400 thread you can see the progress that they've made, in pictures.Are they doing the job?
