Dry-stall vs Horticultural pumice ... was algae and moss in seedling pots

I have used Dry-Stall in the past, and basically avoid it now. It is quite a bit smaller than the horticultural pumice I prefer, and doesn't have the range of particle size I like.
 
Perlite holds much more water than pumice, so could be contributing to the proliferation of moss.

> Is 'Dry-stall' significantly different from Horticultural pumice?  I thought I had hit upon a great thing because it is much cheaper but seems the same as Horticultural pumice I have bought.  I do top with DG (decomposed granite.)
