You don't mention the lighting on your aquarium; do you have LED/MH/T5? Is it possible to lower intensity on lighting to see if that makes a difference?
High input and high output of nutrients is best, so that the corals can get what they need, but can be removed quick enough that algae does not take over. It does not sound like feeding is an issue given the amount you are giving.
