I've been dosing all for reef on my 100 gallon tank. It's still a new tank with only a few corals. I'm noticing at 40ml a day, I'm still dropping alk/cal from roughly 8dkh to 7.3 or by my Neptune 7.3 to 6.9 in a matter of 3 days. I'm considering upping the dosing, but wanted to know if this is normal for a lightly loaded tank to be consuming this much ml a day? Also, I mixed 1500ml ro/di with 8 scopes, so wondering if the strength of the mix is just too weak. thoughts?
