Very unlikely. I had a tank that I only dosed phyto maybe once a week, no feeding, and had lots of macros growing together well. Chaeto, red gracillaria, halymenia, nemastoma, sargassum, dictyota, ulva, and a couple others.
If I had to pick, I'd use chaeto, red gracillaria, and ulva. Chaeto and ulva grow fast, and if you have herbivorous fish they will love to snack on the gracillaria and ulva when you have extra, and all three can grow free-floating. Not to mention that pods love chaeto to live in and ulva to snack on as well.
