Hello, started noticing same reddish/brown algae growing on my sandbed. Seems to stay in the areas of the sandbed that get more light and lesser in the areas with lower light. When lights go out it looks like it reduces and then returns when lights get going the next day. Just wanted to confirm what I am dealing with being either diatoms, dinos, or cyano of some kind. All corals and fish seem to be doing fine.
Tank is 20 gallons and around 6 months old and the current levels are
Nitrate - 11
Phosphate - .15
Calcium - 450
Alk - 8.6
Mag - 1400
Salinity - 1.026
I do weekly 3-4 gallon water changes and these levels are at the tail end of the week before I do the next water change.
