Silphos 0920

[Alex Chen]

Hi Roger,

Are your Silphos 0920 and ROWA-phos from the same source?

I would like to know more about your Silphos such as absorptive capacity.

Thank you.

They are the same basic material but Silphos is a very coarse granule and it is in a natural mineral state, they look like tiny lava rocks. Basically it works the same but much slower and is a long term media that slowly removes phosphate and silicate over a month or more.
