Please help me defeat this algae!

[kimts]

I have a 15g AIO which has been pretty stable. Fish are healthy, coral has been growing nicely, but this algae is driving me nuts. Parameters are ALK 7.8, pH 8.0, phos .1, cal 428, mg 1362, ammo 0, nitrite 0, nitrate 2, sal 1.026. I’ve been leaving the lights off for all but one hour a day, and I’m not seeing a difference. Thoughts on how to eradicate?

Needs pics under white light? Looks like GHA. Do you do daily manual removal? Do you have a complete diverse cleaner crew? How old is the tank?

Hopefully these are better. I have 2 trochus snails and 1 blue legged hermit for CUC. Tank is 4 months old now.

In my 16 gallon I have 4 cerith snails, 4 Astraea snails, a Trochus snail, a conch, and an emerald crab. You gotta up your CUC game!

Algae Identification

Any opinions on what type of algae this is growing on my rocks and sand bed?

www.reef2reef.com

several tank fixes. ideally designed for nano reefs

rip cleans are the cheat to infinite biological lifespans, an unfair cheat large tankers don't have. handle that reef like a mouth that needs a trip to the dentist to remove plaques. the rocks are the teeth, the algae tufts are the plaques. we remove those via target surgery above. over and over. clear pics of the tools and rock detailing and sand rip cleaning are shown.

tank parameters and species id of the algae have no bearing on the fix whatsoever. pure action is what wins, copy above jobs. we have you become the grazer you always wanted, that thorough. a true sand cleaner too

Looks like cyano and GHA which is normal for 4 month tank. Cut lights to 6 hours with blue and uv only no white for a few weeks. Get a diverse cleaner crew with a tuxedo urchin. Daily manual removal and weekly water changes. Raise magnesium to 1500 which helps weaken GHA. Increase flow to areas with red cyano.

What’s the phosphates?

That's fine but nitrates slightly low probably due to algae.
