Dosing schedule

Calireefer92 · May 18, 2022

Hey reefers what is the best time to start you’re dosing for alk, mag and cal? Through out the day?

It's best to do small amounts over a 24 hour schedule but you have to make sure there is enough time between alk and cal doses. Not sure why mag dosing is needed. Water changes cover mag and maybe a small hand dose once every week or two.

I dose mine throughout the whole day, but I do dose more during the times when the lights are on. Generally the demand will be highest when your lights are at their brightest.
Are you going to manually dose or setup a pump?

I dose at night so I don’t have to hear my doser during the day hah. The people above me are right on the money tho.

Mainly during lights on, but some you can dose for a couple of hours after lights off, as the coral do not slow consumption for a few hours. Dont forget to have at least 15 mins between Alk and Ca dosing.

That's what I use. I dose small amounts of alk throughout the day and my calcium doses overnight. 18ml for each currently keeps my alk at 8.5 and cal at 425.

I alternate between alkalinity and calcium every 2 hours, with more during the day/peak lighting.

I have mine set to dose ALK all hours and Calcium during lights? 30 min split in dosing

Calcium hardly changes in 24 hours and so it doesn't much matter when or how frequent you dose it.

Magnesium hardly changes in a week or more, and so infrequent dosing of it (if needed) is fine.

Alk changes a lot day to day and is mostly used during the day.

Some folks dose high pH alk additives during the night to keep pH up, and others dose it during the day to keep alk more stable.
