Tank is doing good.All my corals have finally come back around and there is no more cloudiness .My sand is being over took by this stuff and wanted to know if it was bad

 

Cyanobacteria, lots of posts about it just do a search.

 

Too much light...

I would try to Syphon as much out as I could and cut down on the lighting.

 

I had a small outbreak recently.
I did a 1/3 water change, sucking as much out as I could with the vac
Set up I have and turned a coralia 2 towards it increasing the
Flow there and it was gone in a couple days

 

thanks will give it a try

 

KEEP us posted on your methods and results. good luck

 

Most likely causes are tank's age, flow and nutrients. How old is the tank? What are the params? and what do you have for flow (powerheads and return pumps)? A blackout for 3 days and siphoning can look after it, but if you don't address the underlying cause it will just return. If you can let us know on the questions then we can certainly help you out.

 

Algae problems are usually caused by aquarium water with excess nutrients like phosphate, nitrates etc. You can try and siphon out what you can to remove the algae in the short term. In the long term you may have to examine how you care for your tank. There are some commercial dry foods also contain excess nutrients and other undesirable things like nitrates, phosphates etc so I strain/rinse my fresh/frozen foods before feeding my tank. You may want to consider feeding your fish less often. Also using RO/DI water and a high quality salt with little if any NO3, phosphates etc like Tropic Marin will really help too. Adding a phosphate remover, looking at your lighting (intensity and duration) and increasing flow in your tank may help too.
