How long have you been battling this? Maybe skip the MB7 and just do the coral snow and vacuuming? In my experience, I only got cyano when there was some type of imbalance in nutrients.I’ve been using the snow weekly with water changes but I still have the green cyano building up after a few days. I’m trying to up my water changes but with the newborn it’s been tough. This has been something I’ve been able to distract our 4year old with. She loves helping with water changes.
I did my first online order with Aqua SD for a couple LPS and green bta. I moved around some rockwork to create more space sine the acantho I got looks to be pretty big.
