Hi all,
I know this has been asked probably a million times but I’m having a hard time tracking down a known solution to what I think is green Cyanobacteria.
As you can see in the photo, I have a green mat that’s growing in my sandbed and starting to form on the rockwork.
Tank started in May 2022 (40B with AIO Filter)
Nitrate: 2.5ppm
PO4: 0.1ppm
pH: 8.0
Alk: 9
Ca: 440
Mg: 1320
Salinity: 1.025
Temp: 77
Recently came out of a large GHA outbreak that started in January 2023. Rock/sand leaching phosphates. GHA no longer in tank as of 1 week ago, but am still mildly using phosgaurd to keep PO4 below 0.1ppm (otherwise will rise to 0.15PPM)
Currently moving sandbed/blowing with Turkey baster every other day.
Routine Feeding:
Live phyto (AM) - just before lights kick on
Frozen mysis (AM)
4-5mL AB+ (AM)
Frozen brine (PM)
Routine Dosing:
AFR 4mL (3x/day)
I don’t want to use something like chemiclean and would like to address the root cause of the issue.
Let me know if there is any additional information that would help give context and determine the issue!
Would dosing something like Microbacter7 help? The tank was started with dry rock in May 2022, so would assume it’s “mature” by now. Do I need to supplement beneficial bacteria?
