You aren't the first to be dosing aquavitro fuel (it's a mix of lots of difference vitamins and trace elements) when dinos arrived.
If you decide to go "dirty method" I'd recommend elevating both N and P.
Cyano provides a lot of things that dinos could be interested in. It's an N source, it can capture Fe, and it produces and exports B12.
It seems like in systems dominated by bacteria (carbon dosing, zeo, etc) dinos have an ability to shape the bacterial community to their liking and can thrive to problem levels.
This is a super-crazy-oversimplification but it really seems to be generally true in our systems: call it Rock-Paper-Scissors - Dinos beat bacteria beats algae beats dinos.
If you have lots of algae, dinos don't thrive. If you grow lots of bacteria to outcompete algae, then you are at risk of the possibility of dinos taking control of the bacteria.

Oh, I don't know about carbon dosing + 0 algae spurring on dinos. I've carbon dosed as my main means to reduce nitrates and maintain low phosphates. 0 algae and it's only when I do something stupid that cyano comes out and dinos follow. Otherwise I don't see either. I like to harvest algae but have gone long stretches not doing that either so 0 algae. Vinegar, a skimmer, and consistent water changes has been my constant.
