My tank is a little over a year old now. Started with live sand and marco rock. Use six stage BRS rodi system for water. I have 5 trochus, 8 nerite, and 6 bumblebee snails. Plus 4 scarlet legged hermit crabs for a clean up crew. I can't seem to get rid of this algae. Don't know if it is still some type of diatoms?? This is my first tank so any help would be appreciated. I have had an ICP test done and everything came back normal. Silica was fairly high which I know might cause diatoms. Alkalinity has been stable at 9.2 for a few months now. Ph runs between 8.1 to 8.3. Temp is 77.6. Salinity is 1.025. Haven't tested for nitrate or phosphate because I assume it would be inaccurate because of the algae. First few pictures are under 100%blues with orange filter the rest were taken under 100% whites.
