Okay brain trust, Got a local buddy who doesn't forum but needs some help outside of my expertise. (Cyano)
We set up the tank about a year ago with new live sand, existing live rock and marine pure blocks that have been cycle for many years.
5 ft. 150 gallon running 3 AI Hydra 32's that are two years old. There is Plenty of flow across the sandbed.
N03 stable at 10-12
PO4 stable at .07-.1
Running appropriately sized UV
Homie has been battling Cyano (red slime) for months. It is Only present on the sandbed. Never on the rocks. Vacuuming it out in clumps and it returns the next day.
Done two chemiclean red treatments which only helps for a short time but does not eradicate it. The slime is back in full force shortly after treatment.
I've never delt with or had to battle cyano.
Any thoughts on the problem and ways to tackle it would be appreciated.
