Ill tell you the same thing I was told... Youve got better luck posting that on the Reef Discussion Forum, Prodibio = snake oil in this part of the "woods"...
But IMO: Id do the Digest one week, the next do Optim, the next do Digest etc...
Test with very high precision test kits like Salifert or a cholorimeter(?) for Phosphates...
Once you notice that your Nitrates/Phosphates are at 0units the you may start dosing ReefBooster, but make sure you turn off your skimmer for a few hours while dosing the booster... You'll need to do this once a week I believe...
Someone feel free to correct me if I am mistaken.
