Change your carbon every 30 days and back off your GFO...use it when you need it as for me I use it when my PO4 spikes, very rare for it to do that. If it were the softies the whole corals would be dying and not just the tips. Increasing the water changes should offset the nitrates. What is the temp of the tank?
