I have had disgusting diatoms on my sand for months.nthey won't go away I've added snails nothing changes I don't know what to do. My water quality is almost perfect . Is there anything I am missing? If I add chateo will the pods eat the diatoms ? I stir it up and boom the come back . I'm losing it here I have a gorgeous tank but these diatoms kill it

Nvm the pics I can't figure it out on iPad. But my whole substrate ( sand ) is brown , it's not cyano . If you google. Diatoms. Pic e worst picture and. Ipthts what it looks like

No never really heard much about it or how to use it
You should look into it. It is used to remove phosphates and silicates. I assume you are using RODI water for your tank. If not you should be & if so, you need to make sure you're getting 0 tds water from it.
