How to get rid of these red stuff?
 

Hey guys,

Some red stuff start covering my sand bed , I wonder how could I get rid of them.
They look like Caroline algae but on the sand instead of glass or rocks !

more flow and less nutrients

Its cyano. Is your tank new?

nutrients is controlled ,this is my Seahorse tank and I spot feed them so no leftover food , but I can't increase the flow because of Seahorses. I wonder if I could get something to eat them

They are on the lowest flow part of my tank, everywhere else is ok

easiet way to get rid of it is to siphon it off with a hose of some sort

Hummm :( what should I do ?

It is cyano. It does just show up when the nutrients get too high or not enough flow. The seahorses and corals all exhaust nutirents into the water and if you do not have enough flow, it settles on your sand bed.

Since you cannot increase the flow, siphoning it would be your best bet. It can also occur if your light bulbs are getting too old. Do you run GFO or anything like that?
