Ok as I continue to learn an my tank keeps growing I still have a few questions. My current setup less than 6 months old. 40 gal breeder.
2 k7 mini
2 Nero 3 both set up on right and left side about 2 inches from top
1 tidal 75 set up in middle for surface skimmer
Coral look good I think.
I had green hair algae most is gone but have brown thicker stuff on sand is this the green algae dead and sitting there.
I can show light schedule I believe it’s close to bean but for mini and pump schedule. I will also post picks. Any suggestions ideas would be great. Not sure Nero are in right spot. How do I get rid of the brown stuff on sand. Pics not that good I’ll try light to show better if needed.
