Dosing ? and help

[newbie2]

Hey there, just to get an idea on how much to start at I have about 20 small sps frags that are just starting to settle in and grow and I currently dose 8ml/day of each part of esv bionic 2 part to keep my alk at 8.0. I test everyday to see when it drifts. I started out dosing 5ml/day when I first put the frags in and up'd from there. This is in a 120gallon tank.

I do anywhere from 5% to 10% a week water changes as well.

I also have a nano that has mostly zoas, softies and a few sps frags and I don't dose at all. just 10% water changes a week.

Hope that helps you with your starting point.
