Cyano is usually a result of bad water parameters, low flow and too much light. Try adjusting those three things before trying anything drastic. |
I blacked out my QT a few times as im using LR from the Craigs List guy i got this tank from. It was covered in cyano, and through brushings, and WC's and the blackout it has really helped. There is still a little but i just clean it every week.
I only have yellow star polyps and zoa's so i would not want to blackout my DT unless they would be OK.
I know i need to replace my lights about every 6 months or it can cause issues, but these are only around 3 months old. I also decresed my light time since getting the cyano
I increased my flow since getting the cyano. and there is no dead spots.
My parameters test fine. 0 phosphates and nitrates around 5-10. My Ca and ALK is not perfect yet but im working on that via dosing some supp's.
Its weird to note that once the bryopsis was killed, through me dipping with peroxide, the cyano started shortly after. I didnt have them both at the same time.
I did remove all my media bags as they were dirty. I need to rinse them every week. I didnt replace them yet as the LFS did not have what i need. But i will order them. After a good cleaning and WC on sunday + the removal of the dirty chemipure, purigen and phosguard, the cyano is starting to come back today.
