Need help identifying and eradicating nuisance red carpet/turf 'Alga'(??)

[Dwight]

I have a saltwater reef tank that is dogged by a red turf/carpet algae (or at least I think that' what it is). Can anyone help identify this red carpet looking turf/LR algae. It is easy to remove with a power head but comes back within a week every time. It doesn't seem to harm anything but is unsightly and a downright nuisance!! URGHHHHH

Any help is greatly appreciated.

Thanks.

Looks like cyano, if it blows off and comes back when the lights come on then that's what it is.

Chemi clean will work

From my experience, usually when something dies, (like a snail) I'll see some cyano in my tank.

Thanks. I'll anticipate that it's reef safe. I'll look it up. Willing to try anything at this point.

Agree with trio, looks like thicker cyano

Agree cyano.
Chemiclean will help but need to determine root cause of excessive nutrients.

Im running a 60 gallon sump with cheto and nutrients test low. The one concern I have is the sand bed. When I turn the sand its like a cesspool. I siphon it regularly but can never get to it all because it's a very mature tank with lock and lots of SPS coral that I can;t move.

Over time I hope to eliminate the sand bed altogether through natural depletion from siphoning and water changes.

Do you have any sand sifting critters?

 

[Dwight]

Mostly nassarius snails but I haven't replenished in some time. I had a sand sifting Goby but he didn't live very long.

What type of lighting is over the tank and how old are the bulbs? Just curious because I see it’s affecting your birds nest so it’s it’s halides that are old that could attribute to it.
