Review on Seachem PhosGuard 100 mL Bagged - Product Review, Benefits, and Usage Guide by Ahmed Morrison

I had a big problem with diatoms. I've never had big spikes in nitrates, so I figured my water and the silica in the sand were to blame. After adding the filler, I wiped down the glass and mixed the sand, then increased the water flow from the tide filter and printhead to circulate the debris. After a week I have no signs of diatom growth! It's still minimal in my small tank, but I didn't stir the sand like I did in my 55 gallon tank, but I'm happy with how clean my tanks are now!
