Im about 5 months into the hobby and I have a JBJ65G tank that’s been set up for about 2 months now, at first I got brown algae all over my rocks and now I’m starting to get green algae, it’s not hairy at all what’s causing it, is it the precursor to coraline algae

Any help would be appreciated

My tank JBJ 65g
Bubble magnus 3
red sea nano mat
Upgrade dc return pump



Fish
2 chromis
2 clowns
1 Niger trigger
1 orange stripe bristle tooth tang
Whole lot of clean up crew


Current parameters
Salinity 35.8 ppt(1.027)
Alk 120
Phos 0.2
PH 7.9
Ca 432
Mg 1229
Ammonia 0
Nitrite .1
Nitrate 10

Could just be one of many species of micro algae. Maybe nothing to do with coralline.
 
looks like standard green microalgae to me, not a cause for concern in a 5-month old tank. just ensure you have sufficient cleanup crew (trochus snails are awesome), and perhaps endeavor to reduce phosphates a bit. at 10 nitrate, you generally want ~0.1 phosphate.

HOW MUCH DOES A FISH’S FEEDING REQUIREMENTS AFFECT YOUR STOCKING DECISIONS?

  • A lot! - I avoid fish that require frequent or specialized feeding

  • Not much. I’m willing to adjust my routine

  • Not at all. Feeding demands don’t limit my stocking choices

  • I usually learn about the demanding feeding schedule after buying the fish!
