Only the cyclops were taken in, but they also eat it when it's just dumped in
So, I stopped trying to spot feed

I'm adding coral vitalizer daily while the return pump is still on ( probably some of it is being wasted, but I don't like turning off my return as it upsets the balance in my chaeto tank )
I feed coral frenzy 2-3 times per week, and turn the pump off for 15mins
Last night, for the first time, I fed powdered phyto, and 15mins off
I'll probably feed the phyto at the same time as the frenzy
