Help Wanted : Algae Bloom

[Peter Peng]

My tank has been up for around 2 and a half months.
I have a skimmer and a phosban reactor running biopellets right now

I have a purple tang, and 5 anthias

I feed mysis usually 2 - 5 times a day due to my anthias

I have my lights on for 12 hours a day

Phosphates around 1ppm and nitrates 1 - 2

Ive been getting lot of this algae on the sand and on the rocks, none on the glass

Im not sure how to remove it so any help will be appreciated

I think its Dinoflagellates

make sure it's not Cyano before you start to diagnose.

Looks like maybe Cyanobacteria on the sand and Dino on the rock. Dinoflagellates looks like slimey snot. Is it slimey snot-looking on the sand? Can't really tell for sure from the pics.

Looks like Cyano to me.... Or at least the cyano I have
I get it on my sand from a serious lack of flow in that area, and on areas that have been stung by other corals.
That seems like some heavy duty feeding for anthias...

The bubbly, snotty stuff in the pic with the green rhodactis mushrooms and toadstool is dinoflagellates, but the stuff on the sand is cyano IMO. Good luck cleaning up this mess

Try rinsing off your mysis before you feed it. The nutrient-rich juices are probably fueling the nasties.

Thanks for the help,
I did a 15% water change just now and sucked all the algae off from the rocks. The algae on the sand is still however covered.

I adjusted so my rocks get more flow but I will look into powerheads to make sure my sandbed has enough flow
