Tangs eating trend

[o.c.d.]

So I have some older tang (Sailfin, Regal,Yellow, Foxface) and they have stopped eating nori or grape calurpa. id like them to start again bcause i have macro algae growing in my display and its starting to choke out corals. I feed my fish well and i think that might be part of the problem. Any insight would be helpful

Feeding a lot of one, may lead to not to much eating of The other.

i would cut back a little to see what happens in a few days
