I've been asking myself and others this question for weeks now. Acropower sounds legit, I saw another reefers tank that had good growth from it.
I asked an employee at New Fish on Milwaukee what they feed the corals in the main DT in the back. He said rods coral blend mixed with seachem reef plus, and phyto whenever they have it freshly made by one of their employees who cultures and sells it, apparently.
So, I am currently going to try Rods Coral blend, its supposed to contain smaller sized items than the original and does Not contain the large fish only food that SPS won't take and the i.e. broccoli/carrots, which is not natural coral food.
I am also going to buy the Rods fish Only food. This way by having the coral only blend and the fish only blend I figure I can control who is getting fed, fish or coral, otherwise I feel like I'm just making a mess since the fish can't eat the tiny coral food and the coral can't eat the large fish food. I'd rather have it already separated for me.
Lots of people use things like oyster feast, Roti feast, reef chili according to my google searches. Its all just opinions, including my own.
