Diatoms tend to come and go as they please. Is this a new tank? If so, it's all part of the normal process. new tanks are high in silicates from the fresh silicone used to seal the tank edges. Diatoms thrive in silicate-rich environments. If all part of "New Tank Syndrome" to let them consume the silicates.

You may also have silicates in your source water. Some believe that running phosban or GFO will help to remove the silicates from the water, but I haven't been able to prove this yet.

Its not a new tank though i actually was using it for a freshwater tank for about 4 years before i started the salt water one a month ago or so i drained freshwater and put saltwater in then away i went....

Just let nature take it's course (Let the diatoms burn themselves out).

I agree, it will go away, nothing to worry about.
