Never dose until you have tested for what you're dosing.
If you're dosing a two part system try to to dose a couple hours apart. I dose Ca in am and alkalinity component in pm.
Dose into the sump or hi-flow area to promote fast dilution.
What are you dosing and why?

I use Kent Two Parts AB. I want to dose because this moringing i test my parameter and my alk is at 6.2(red sea test), cal is at 390( red sea) (400 on API test). My always like to run at 8 for alk and 450 for cal. I guess my corals start using alk and cal to grow since i have very low N (0) and P (.02) in my tank. Lets say if i need 100ml for alk and 170ml for cal. Do i dose alk all at once and couple hours later dose cal all at once. That what make me confused.
In order to dose you need to test and determine what your tank is consuming. That's where a dosing pump comes in handy. With it you can dose small amounts throughout the day keeping parameters nice and steady. You don't want to dose all at once. You want to bring levels up slowly as not to stress corals.

Dosing alk all at one isn't usually a good idea bc your ph will spike. Definitely don't dose alk and cal together...that will cause precipitation.

If you can afford it, dosing pumps are a lifesaver in this area.

If you have a dosing pump, then that makes it very easy. You'll want to set it up so that it's dosing your tank throughout the day (mine doses 8 times a day). You can alternate the start time on doses so that there's at least an hour between alk and cal doses. HTH

I use reef chemistry calculator and this is what i got kent two parts ab. I need 43.7 to reach 8 on alk and 170ml to reach 460 on calcium but how should i dose it and how many time per day.

I'd dose even parts throughout the day, and split them into say 6 or 8 doses during a 24 hour period. I'd set it so the alk gets dosed an hour or so before (or after) the cal each time.

Yep. In fact that's the best way to do it bc it maintains stable levels throughout the day.

Yep, but you already know how much you need to choose overall, so all you have to do is divide that by the number of doses and that gives you the amount for each dose. My bubble magus dose actually does that for me.

This is what im gonna do. According to Reef Chemistry Calculator I need 43.7ml of part B to reach 8ppm on alkalinity and 43.7ml / 6 times a day= 7.28ml. I need 170ml of part A to reach 460ppm on calcium and 170ml / 6 times a day = 28.3ml. Am i calculated it right.
First you need to know what your daily consumption Is before dosing. Test your parameters and slowly get them where you want them and then go 3 days without dosing and retest. Divide test results by 3 and that will tell you your daily consumption. Then you can go to the reef calculator and determine how much to dose each day.I have my doser set to dose 24 times a day for calcium and alkalinity. Most dosing pumps will spread out dosing between the two so they don't dose at the same time. I think your calculations are off unless you have a very large tank with lots of coral. That seems like way too much to me. Also most of us make our 2-part much cheaper.
