Hello ,can someone please tell what the he'll is going on with ORP levels at my reef ?
It's 850 liters of reef , 3.5 months old.
2 weeks ago I replaced active carbon from red sea to ATI.
I also started dosing DIY no3 and po4.
I can't find any reason for such drop at the ORP levels.
For some reason the PH levels started to climb up .
I also have refugium with cheato.
1 month ago the ORP levels was 400 to 450 .
