Green Algea on Sand

[Aqau_Dude]

Hey Everyone,

So i moved from my old tank to a new waterbox frag 105. I used new marco rocks and sand for the tank. Its been set up and has been running for a few months now. First i had diatoms that went away.

Now im dealing with green algea al over the sand bed. Whenever i clean it up its back the next day. Im not sure what this is and how to get rid of it.

My parameters:
Temp: 25c
Salinitiny: 35
Alkin: 8
Magensiun: 1400
Calcium: 440
Nitrate: 7
Phosphate: 0.07

The thank is running with a skimmer, a reefmat roller fleece and a fuge in the sump. I noticed that the fuge also growns hair algea?

I would try to add some more clean up crew. Nassaurius snails, maybe an emerald crab.

i have multiple nassaurius snails. Last time i had a emerald it was eating my zoa's so not sure if i want to try that again. But you think this is oke and should be left alone? Everytime i vacuum it its back the next moring.

Does it look like what was on my rock back in 2021? The green came shortly after the diatoms and lasted about 6 weeks and went away on its own without intervention. I believe it’s just a normal part of a new tank. Wouldn’t hurt to toss in a tiger conch if the color bothers you, it will keep your sand bed nice and white.

I would also recommend having the lights on less and for the emerald crab you can try it again but it may have the same problems.

Thanks for the tips guys. So i noticed yesterday that there was a bit of red algea on top of it. It seemed like cyano. Keep in mind this tank has been running for a few months now. So i vacumed it again yesterday using the Eheim Quick vac with floss in the chamber. Today the green algea is back less then 12 hours.
