Any new saltwater tank will go through a diatom phase. They'll normally die back as the tank matures.
 
Sweep it up with a net or you can get a water vacuum( which is better in the long run) but it will go away with time.

My tank is almost a year old
 
Diatoms feed off of silicates which are not usually found in your water. Have you changed your light bulbs and/or lighting schedule?
 
Get a same shifter star fish and or nasserus snails my tank die that still i added 6 nasserus snails and 2 sand shifter star fish

Try cutting back 1 hr. Do you have anything that stirs your sand?
 
Only a fighting conch, i need nacaruis snails, the bulbs are 6 months old, is that too old? Ive read that the time frame is 9-12 months
 
Also- did anything happen to the tank to cause a mini cycle? This could also of caused the diatom bloom.

Your bulbs may be reaching the end of their life- just make sure to switch them out one at a time so if you have corals they can adjust to the new lighting

nope, perfect water parameters, but then again the algae cood be eating the nitrates before my test kit reads them, but i do atleast a 15% PWC every week so they should be low.. btw my bulbs are t5HO
