Hi I am pretty sure this is diatoms. Tank is about 3 months old. Here are my latest parameters:

Ph 8.1
Am 0
Nitrite 0
Nitrate 15
PO4 .03
Temp 78
Salinity 1.025

Have had them now for 5 weeks. When you blow on them with a baster turns into powder/dust like. I think I'm just paranoid after ready about dinos and seeing all these threads regarding them any help to a noob os mich appericated.

Have whites on for 2 hours then blues so another 6.
