You can but it makes better sense to dose at different times. I dose alk at night after lights out to help keep pH up and Ca during the day. Ca and alk when mixed together form a solid so it's wise to dose them separately.

yup....dosing both at the same time will cause a snow storm in your tank......like Lance said best to dose at different times of the day......or better yet with a dosing pump

If you have to dose them at the same time, dose calcium first and wait 30 minutes before dosing alkalinity. Make sure it is well diluted in the tank before it hits the corals, as the slurry will instantly burn the corals.

Dosing pumps really are the best way to go. I used to dose manually and hated it. I use a 5 liter Bubble Magus container for each. Fill them up and I'm good for 3 weeks.

Hounestly i does alk and then 2 minutes later i dose the calcium. If you do it in a high flow area they will dissolve alomst instantly.

You risk precipitation by dosing together. Jason if you are using builder and advantage... which I thought you were... the instructions I believe indicate dosing should not be done together.

Alterante days.... just test and be diligent with dosing.


You could also try better salt. Since I started using H2Ocean my clacium never drops. Kh is all I dose now.

Ditch the Instant Ocean!!!!!

I wonder... does anyone care enough to read signatures if you make them really small? I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds.

I'm seriously starting to consider different salt. But first I should finally learn to dose my tank on a regular basis. I've been depending on my salt too much. I've found that Ca and Alk levels in my tank are dropping way faster than I thought. I didn't realize that little frags could suck up so much.

Your rock also absorbs elements. Coraline algae my friend.

Hounestly just dose one and wait 5 or 10 minutes and dose the other, if you get parcipitation i will be beyond shocked. Make sure its in a high flow. I have to dose daily because my sps grow like weeds and i have never had a problem with it. CAL 440ppm alk 7.5 dkh
