Do you manually dose? What do you dose?

My tank is seeing more and more SPS these days, and I'm curious what I could use to promote growth. My corals don't really spread, or grow all that fast.

Have you found after using a specific product, you've noticed different results in different areas?

I've been dosing Aquavitro fuel recently to try and promote coral growth and polyp extension, but it really doesn't do anything significant from what I can tell. I don't dose the 3s, as my water parameters are absolutely spot on, with no detectible NO3 or phosphates, and don't want to add to the pollution.

Do you just do the big 3's for stability? Do you dose different things for different reasons? Have you stopped using a product, then noticed a different, so you started using it again, or stopped a product completely?
