Thank you, yes I'm trying. I have lights on only 5 hours, a 40w uv, and I took out the filter sock and turned off the skimmer. Feeding more also. Any thoughts on the silicate dosing? Raising temp to 82, adding mb7?Try to raise your nutrient levels ( nitrates and phosphates if the levels are low) in order to foster growth of some competing algae. Also try to reduce the light schedule as well. Avoid water changes in the meantime while raising nutrients.
