I have a BioCube 29 that has had a GHA problem for months now. I installed a skimmer and started running GFO but all that did was slow it down some. Next step was Vibrant which really did a number on the GHA, but since Vibrant's bacteria strain reduces nitrate and phosphate, my corals began starving. My Sunburst Monti went from vivid orange to a shade of orange so pale it's almost white. I made a thread here about it and everyone said feed more (I feed 2 fish a small portion of LRS once a day). So I did, and basically all i'm doing here is feeding my GHA since it snatches any and all nutrients from the water column immediately.
If I began dosing Vibrant again but started dosing with the KNO3 I have left from my planted tank days, would I be adding fuel to the fire? I'd really like to get my nitrates up some without also adding phosphate.
Edit: I should add that I do weekly 25% WC with Reef Crystals so I believe nitrate is my only limiting factor at this point.
