You need to dose the NO3 up. That ratio is dangerous for problematic algae and Dino’s. Get some Loudwolf Sodium Nitrate (NaNO3). I can help you make a safe solution for your tank and tell you exactly how to dose it w/o running into any issues at all. I can tell you how many to buy depending on your tank size. Just PM if you need help.I have been watching the No3 for the last few weeks daily, if I skip coral feeding it will drop. Today’s No3 is 3.4ppm but phosphate is 0.76ppm. If I even walk by the tank with GFO the Dino get happy. I haven’t had a Dino outbreak in about a year.
