I have done the following
Oyster feast
Roti Feast
Phyto feast
Target feeding w/
Rods Reef
Forzen Mysis.
The oyster feast and target feeding were the only 2 i noticed benefits from.
When i feed oyster feast my zoas/palys change color (metalic colors, and the neons pop and there mouths open real big)
When i feed directly, within a couple hours of eating they look REAL fat and healthy.
I noticed better growth and color when doing both.
I stopped using ReefNutrition products though because to much phosphate and causes algae.
WM amino acids i have used as well, W/ the target feeding but i dont know what the benefit is. I can't tell since i target feed as well.
I also know if used to much Amino acids will also give you an algae bloom.
Now i stick to just target feeding once a week.
Hope that helps.
