I had something similar. I am thinking I had Dinos. I tried blackouts. And even spot peroxide . Months and nothing changed. I ended up emptying the tank of animals and water to about an inch above the sand.. I threw out the arag alive sand and water. I rinsed with rodi. Then added caribsea ocean direct sand. I returned the water, filtering it with a sock. I've not had an issue since then. Thoroughly pleased.
