Help!--bad case of diatoms/algae

[FishmanJosh]

Not sure where to put this but I have a very bad case of diatom HELP!
Tank has been cycling for around a week, all levels are fine now apart from nitrate whhich is around 15 (this is a reef tank so working to get it down to 0ppm) Here are some pics:





Any help on getting rid of them will be geatly apprectiated.

If your ammonia/nitrite spiked and returned to zero, then add some trochus and astrea snails. They'll enjoy the snack. The diatoms will also burn themselves out, but it always takes longer than you'd expect.

Yeah, the Diatoms will eventually leave by themselves as long as parameters are good. Used to drive me crazy

question?

IS it normal sometimes to not ever have a full diatom bloom?

Did you use tap water?

No, I used RO.
