I also have been dosing Av fuel, yet to see results switching from acro power, in regards to the algae bloom, it’s inevitable, blow them off and make sure you have proper flow. Dosing other thing such as carbon source ( No3Po4x ) to get rid of the problem I believe causes more an issue, let fuel do what it’s supposed to do, it’s an amino acid. If algae persist cut the dose in half, happy reefing.
