What is a safe ALK swing though the day I tested 3 times yesterday.
Hanna
9:00 am 10.32 Alk
12:00 pm 9.84 Alk
6:30 pm 9.74 Alk I also tested CAL at 450-460 ( Red Sea) PH 8.08-8.20
I dose 2 part BRS (35 ml CAL and 35 ml ALK) I have a 90 gallon tank with 40B sump total water 110 gallons. My Apex dose the CAL in the day and the ALK at night the ALK stops 6:00 am. So does it look like I have it stable ? or do I need to still work on my ALK. The tank looks good and the corals seem happy.
