All/Calc consumption

[Pete Luna]

I have been trying to get my Alk and Calc to stabilize. I run a kalkstirrer 2000 mL a day, I dose two part at 41 mL a day my numbers have been on a steady 1 dkh drop per day, so I am steady increasing. My tank is SPS dominate, it appears I am growing more coralline algae than anything, how do I stop, take out rock?

tank info
250 gal system
T5/LED combo (black box) 16 hr cycle
I run an Apex with a Trident and Reefbot for Phosphates, Iodine
ALK = 8.54
Calc = 457
Mag = 1361
PH = 8.23
Salt = 35.2
Temp = 37.5
nitrates = 10ppm
phosephates = .02

Higher alkalinity consumption is a good thing. It just sounds like your tank is doing great! I run a 180 gallon tank and dose 4.5 liters of kalk per day. Plus am up to 70 ml each 2 part. And climbing!

Thanks, increased Kalk to 3000mL seeing a little bit more stability.

You want to grow less coralline?

If you let alk drop to 7-7.5 dKH, the daily amount needed to keep it there will likely be less.

Coralline is fine, seems like as I increase Acro growth stays about the same but Coralline is a lot
