More flow won’t really help in the long run with cyano. You are probably just low on nutrients and the tank is still young.
Switch to regular instant oceanPlanning to battle Cyano with water changes to lower nutrients. Have been with 25 ppm nitrate and .1 phosphate for about three months. Problem is, I target 8.5 Alk and my reef crystals spike it with every water change. So, two options: small water changes to keep the spikes low or switch salt and do larger changes. Thoughts?
