Coral Snow is a fine clay mixture that acts as both a flocculant and a pH stabilizer, I believe.
As a flocculant, its clay particles adhere to the little bits and pieces floating about and then they are skimmed out by your skimmer. The clay has a secondary effect of neutralizing acids in the water column preventing lower pH which would explain why it also has an effect on cyanobacteria. |
