I have been using Probidio BioDigest + Bioptim and have been extremely satisfied with the result.
I starting using Prodibio products around Sept 2011.
My brown chalices returned to their brilliant coloration and my other SPS have started growing fast with great coloration.
The negative of Probidio - diatoms.
At first I thought is was just part of the initiation to Prodibio.
I went on a few forums and found some of the same concerns - but no explanation.

I decided to do some of my own investigation into the why.
The first step was getting my hands on a silicate test kit - as diatoms & silicate go together like GHA & phosphates.
I tested my R/O, tank water, and a fresh bucket of saltwater - all tested zero for silicate.
I also run Rowaphos in phosban reactor - which makes the diatom issue even more perplexing.

My next step will be to dilute the Probidio products and test them for Silicate.
I will also be contacting Prodibio to determine the cause and solution for diatoms.
