So you used waste away and refresh correct? I've thought hard about trying this. Did using those products do anything to your NO3/PO4 levels?I'm declaring VICTORY!
It took 3 courses of Dr Tim's regimen and a final 3 day blackout to wipe out the remainder of the dino's and the residual algae, but the tank is IMMACULATE right now. I think what pushed it over the edge was the 25% WC last weekend followed by the 3 day blackout. I was dosing Neophos and Neonitro continually trying to keep nutrients above zero. The 72 hr blackout remedied that, but it did take a toll on several of my SPS, particularly the Jack-o-Lantern. Half of it melted. Hopefully good husbandry will result in a rapid recovery. I'm very optimistic.
In summary, hang in there! Mulitple iterations of the treatment may be required. Each time the dino outbreaks were smaller and smaller, but eventually I was able to out-compete it with bacteria and algae...
