No. Adding labile DOC, aka carbon dosing, may be helping the algae actually (See Rohwer's links and the links on phase shifts below). The algae eaters I like are urchins, large algae eating hermits like thin stripe hermits and sally lightfoot crabs. IWhat has worked best for me over hte decades is doing consitant water changes and manual removal and FWIW I haven't seen any correlation with nitrates, phosphates and nuisance algae. Shifting ecosystems so they don't promote nuisance algae doesn't happen overnight so be patient.
"Coral Reefs in the Microbial Seas" This video compliments Rohwer's book of the same title (Paper back is ~$20, Kindle is ~$10), both deal with the conflicting roles of the different types of DOC in reef ecosystems. While there is overlap bewteen his book and the video both have information not covered by the other and together give a broader view of the complex relationships found in reef ecosystems

Differential recycling of coral and algal dissolved organic matter via the sponge loop.
Sponges treat DOC from algae differently than DOC from corals
