It’s a Red Sea 250. 2 year old live rock and new sand bed (2-3 months). Essence 130 skimmer. Had a bag of gfo, and took it out a few weeks ago when what looked like dinos showed up. Still can’t boost phosphate (all reef roids did was algae bloom and cyano)Yes it does. And it’s a long battle with cyano Dino. You feed a lot you get cyano because now that you have increased the lower nutrient the system go out of whack. Bacteria consumes No3 and Po3 in a ratio what size tank is this ?
Thinking I should dose a bit of phosphate?
