Thank you. If it wasnt being absorbed then I guess I'd see Mg being depleted fairly quickly. I'm planning on rerouting my alk dosing line to right in front of my overflow weir to ensure better mixing. Just to rule out that possibility.
Elevated PH, Elevated consumption. How much?

I'm not sure what to tell you other than you may just have amazing hard coral growth. Everything seems to check. Your calcium and alkalinity consumption seem to occur at the correct ratio for coral growth. The consumption occurs even when not dosing which pretty much rules out precipitation at the levels you are seeing. I'd run one more solid test to make sure alk and calc are dropping together at the expected rate. If they drop together again I open a store to start selling coral frags because you must be growing them like weeds!
Oh, and switch to a calcium reactor, you will struggle to keep up dosing at these rates soon!

Will check what the alk is when I get home. Some of my corals are really taking off while others are a bit slow. I will however take my CO2 scrubber offline and start dosing again to see if the levels stabilize. I dont think I'd ever want to go into the coral business. One small equipment malfunction or a long power outage and your entire inventory can be wiped out!
Ive only dosed sodium hydroxide and the levels were pretty stable at 8-8.5dkh. When I decided to up the level to 9, i had to make some small adjustments. The problem really started when I put the CO2 scrubber online. If taking the scrubber offline still gives me problems, switching to dosing baking soda will be my last resort. I prefer to stay with sodium hydroxide as it keeps my PH nice and high.
I meant only while you track the daily consumption then switch back to hydroxide. That way you pretty much take pH based precipitation out of the equation so you don't get into the cycle I was in where you add more hydroxide, you are increasing the pH a lot, get precipitation, add more hydroxide pH goes up... repeat. Since pH is a huge driver of precipitation it might be worth eliminating that possibility although seems like you have a pretty good handle on things now.
