First time with actual lights on an aquarium and the uglies are rolling in on schedule. Expected, and with it brings more stuff to learn.
I’m curious about what this red coloration is that has developed on the rocks and sand where it got a foothold before the green algae, also on the glass but I clean it off. I have a grow light in the sump, but in there I only get green algae, so assume I’m getting different growth due to different lighting (much bluer in DT)
My first impression is cyano?
Nitrates: 30
Phosphate: 0.5
Lights:
DT: Noops at 30% except green and red at 5%
Sump: Grow light (lots of red)
Photos under plain cool white light from the DT lighting.
