Could anyone ID this algae, and recommend a way to get rid of it. Tank parameters are all great. Phosphate - to low to read, Silicate - to low to read, Calcium 450, Alk - 13 DKH. The algae peels up pretty easy but grows back. siphoning is difficult as I loose a significant amount of my sand and the algae seems to still come back. Thanks for any help.
